                   Using the program Moles

     When students are first presented with determining gram
formula masses and the mole concept there can be a lot of confusion
and frustration.  This program is designed to make learning this
concept easier for the teacher and more fun for the student.  It
can be presented in either a manual or automatic mode for students
of various backgrounds and abilities.    

Installing moles on you hard drive.
     Start windows and click on Start in the lower left hand corner
of Windows 95.  Select Run then type and enter A:\install.
If the source files are in a different drive then substitute the
drive\path for A:\.  Install will copy the program files to your
hard drive, create a Program Group for moles, add Moles to your Programs Menu and create the appropriate icons.

Advantages of registering:
     When you register (see register.txt) you will receive a total
of 7 different substances for both the auto and manual modes. 
Registration costs $10 + $2 shipping and handling.  This fee
entitles you to a site license for the program and a copy of a lab
which can be used with the program will be included.

Using Moles:
     From the Calculation menu select new or press the F2 key.  To
exit the program select exit or press Alt-x.  You may select Auto
or Manual from the Mode Menu.

Auto Mode:
     When F2 is pressed in the Automatic mode a dialog box will be
presented which is used to choose the substance to be dealt with. 
The gram formula mass for the selected substance will be presented.
A starting quantity then must be chosen so that the conversion
portion of the program can begin.  To choose a starting value
either click on the new mass, new moles, new molecules, or new
volume boxes in the upper left hand corner of the window or choose
random value.  A number will appear under mass, moles, molecules
or volume.  To start the conversion process click on the calculate
box and the problem will be worked out.

Manual Mode:
     When F2 is pressed in the Manual mode a dialog box will be
presented which is used to choose the substance to be dealt with. 
The formula and a series of element windows similar to those on a
periodic table will be presented. To find the gram formula mass of
the substance the correct symbol must be clicked on the appropriate
number of times.  A number will appear under mass, moles, molecules,
or volume and a qwuestion will appear asking the user to perform a
conversion using the conversion factors that appear.  
      To solve the problem the student must click on the correct
conversion factor(s) in the correct order.  When the correct
solution is selected the numerical answer is calculated
by the computer and it is displayed on the screen.  New questions
will be asked until the entire table is complete.

Mode Menu
     When Auto is selected the gram formula mass and conversions
will be done automatically for the student.  This is a good place
to start when finding molecular weights and doing conversions has
just been introduced.  When manual is selected the student finds
the gfm by clicking on the symbol of the appropriate elements the
correct number of times.  Conversions are then done by clicking on
the appropriated conversion factors in the correct order. 
        

Random Value
     When this is selected a random value for a mass, moles,
molecules, or volume(if a gas) will be generated.  As an
alternative a desired value can be entered by clicking on the new
mass, new moles , new molecules , or new volume boxes in the upper
left hand corner of the window.

 New Mass
     Click on this box in the upper left hand corner and a dialog
box will appear.  Enter the value of the mass desired and then
click the left mouse button on the substance you want to assign
this mass to.  The value will appear in the grid below the
substance.  Click the left mouse button on this quantity and then
click the right mouse button on your goal.

New Moles
     Click on this box in the upper left hand corner and a dialog
box will appear.  Enter the value of the new moles and then click
the left mouse button on the substance you want to assign this mole
value to.  The value will appear in the grid below the substance. 
Click the left mouse button on this quantity and then click the
right mouse button on your goal.

New Molecules
     Click on this box in the upper left hand corner and a dialog
box will appear.  Enter the value of the new moles and then click
the left mouse button on the substance you want to assign this mole
value to.  The value will appear in the grid below the substance. 
Click the left mouse button on this quantity and then click the
right mouse button on your goal.

New Volume
     Click on this box in the upper left hand corner and a dialog
box will appear.  Enter the value of the desired volume and then
click the left mouse button on the substance you want to assign
this volume to.  The value will appear in the grid below the
substance.  Click the left mouse button on this quantity and then
click the right mouse button on your goal.
