Materials Calculator

This simple implementation is meant for the easy calculation of reactants amount when the product amount is given.

This was created on Mac OS using python 3.X.

Dependncies: re

Usage:

1. Enter the product formula
2. Enter the amount in gram/milli-gram
3. Confirm the inputs
4. Enter the units desired
5. Enter the number of reactants
6. Enter each reactant formula

Assumptions:

1. Each element that is not {H, C, O, N} can appear only in one reactants
2. The formulas are simple, meaning that there is no brackets etc.
3. It only support gram and milli-gram for now.

Dummy Example:

Please provide the desired product formula: Li7La3Zr2O12

Please provide the desired product amount: 1

product: Li7La3Zr2O12 amount: 1.0 is this correct? [y/n] y

Which unit of measure for the amount entered:

1 - gram 2 - milli-gram

1

How many reactants there is?

answer: 4

Please enter the 1 reactant out of 4 : Li2CO3

Please enter the 2 reactant out of 4 : La2O3

Please enter the 3 reactant out of 4 : ZrO2

Please enter the 4 reactant out of 4 : Gd2O3

The reactant Gd2O3 is unnecessary

<===========================================>

The amount of each reactant is as follows:

0 : Li2CO3 - 0.3079699574035328 gram

1 : La2O3 - 0.5819812299268465 gram

2 : ZrO2 - 0.293476202781572 gram

3 : Gd2O3 - 0.0 gram
