ChemCalc: A Scientific Calculator

Note:
This program is out of print.

ChemCalc is a scientific calculator program that can be used stand-alone or incorporated into other software written in BASIC. Like a typical scientific calculator it allows students to evaluate arithmetic expressions entered from the keyboard; numbers and operators are entered; and pressing return gives the numeric result of the calculation. In addition, ChemCalc knows the atomic weights of the elements, Avogadro's number, and some useful constants. Whenever an atomic symbol is found in the expression to be evaluated, the atomic weight is substituted. Likewise, the gas constant is substituted for R, Avogadro's number is substituted for A, 3.14159 is substituted for pi, etc. This makes easy entry of expressions to calculate the weight percentage of an element in a molecule or the molecular weight of a compound.
Hardware and Software Requirements
Programs in this issue are supplied on 5.25-in. disks and will run under MS-DOS (IBM PC DOS) version 2.1 or later. ChemCalc requires 256K RAM and one disk drive. To use ChemCalc as a subroutine in your own program you will need BASIC.
