Reaction yield calculator

To use the yield calculator:

Select whether you want to work in grammes or millimoles
Select a yield multiplier (must be anumber, normally leave this set to 1.000)
Enter chemical formulae for starting material and product
Enter quantities for starting material and product
Select "Calculate now" to execute the calculation

	Starting material	Product
Enter a chemical formula (see notes below, case sensitive) into each box:
Enter a weight (must be numbers in grammes - don't write in the units) into each box:	g	g
Enter a yield multiplier, which must be a number, usually 1.000):
Calculation status: (will appear here)		Yield: (will appear here) %

Notes

The formula is case sensitive. So h2o will fail but H2O will work
Correctly nested brackets [{()}] are OK
pseudoelements such as Me, Ph, Cp are OK
Compound names and element names such as water or iron are not OK
