You are assigned to make a medicine for a certain disease.

Question

Continuation... After countless days of researching on how to make the required medicine (let us name it chemical Chem) you have found out that you need to combine chemical A and chemical J. Applying some mathematical computation, you have computed that if you combine 2 moles of chemical A and 2 moles of chemical J, you will produce 3 moles of chemical Chem. Question No. 1 How many moles of chemical J do you need if you plan to make 6 moles of chemical Chem?

Answer 1

2A + 2J ==> 3Chem ... balanced equation

6Chem x 2J / 3Chem = 4J

So, to make 6 moles of Chem, you would need to use 4 moles of J.

The molar mass of J = 6x12 + 18x1 + 2x14 + 1x16 + 1x32 = 72 + 18 + 28 + 16 + 32 = 166 g/mol

6 mols Chem x 2 mols J/3 mols Chem x 166 g J/mol J = 664 g J
