INTRODUCTION

The element symbols can be written in lowercase letters, and the intelligent routine in the program will try to translate them and will show the result of translation - or it will report an error. The appearance of mathematical expression, which is the result of the translation, can be seen if the mouse pointer is held over the entry field. The right mouse button has several often used anions and molecules.

The calculator feature is a list with task history in that storing all of your recent inputs and results. Chemistry Assistant also included a detailed help file that containing syntax, usage, and examples for all of the supported functions. The calculator also provides a list of common physical constants and performs various conversions between English and metric units.

Every function that is supported by Chemistry Assistant can be inserted by clicking on the button with function name or type its name on the physical keyboard. Some functions are not associated with the buttons, but every function can be called by typing its name. Examples are available from Help menu.

For example, when calculating the relative molecular weight of a copper(II)sulfate pentahydrate, type

cuso4+5h2o

And the smart converter will translate this text in the correct chemical formula

CuSO4+5H2O

If the chemical formula contains a mathematical operator (such as +, *, /, ...), smart converter will automatic add the parentheses in the expression

(CuSO4)+5*(H2O)

The next step is the change of chemical symbols with the molecular weight for each element

(63.546+32.066+15.9994*4)+5*(1.00794*2+15.9994)

The last step is calculate this created mathematical expression

(63.546+32.066+15.9994*4)+5*(1.00794*2+15.9994) = 249.686

and display task and results

Since the relative atomic weight of cooper given above only has 3 decimal place, accuracy cannot be determined beyond that point.

Here are the sample tasks:

8.12E-5/2 = 0.0000406

sin1.5 = 0.9975

log(20*5) = 2

5! = 120

15%60 = 9

x^2 + x - 7 = 0 = x1 = 2.19; x2 = -3.19

H2SO4 = H*2+S+O*4 = 1.00794*2+32.066+15.9994*4 = 98.079

cuso4+5h20 = (CuSO4)+5*(H20) = 260.4036

104.4/(mn(no3)2+6h2o) = 104.4/(Mn(NO3)2+6*(H2O)) = 0.3637
