Can you help me figure out these moles? I'll give 10 pts to best answer? :)?

Question

Carbon disulfide is an important industrial solvent. It is prepared as follows 5C +2SO2 ----> CS2 + 4CO

a) How many moles of carbon disulfide form when 6.30 moles of carbon reacts?

b) How many moles of carbon monoxide are formed when 0.762 moles of carbon disulfude are produced? :(

Answer 1

a) How many moles of carbon disulfide form when 6.30 moles of carbon reacts?

5C +2SO2 ----> CS2 + 4CO

According to the balanced reaction equation given above, the mole ratio of carbon and carbon disulfide is 5:1
Thus, 6.30 moles of carbon will react to produce
6.3 / 5 = 1.26 moles of carbon disulfude

b) How many moles of carbon monoxide are formed when 0.762 moles of carbon disulfude are produced?

According to the balanced reaction equation given above, the mole ratio of carbon disulfide and carbon monoxide is 1:4
Thus. if 0.762 moles of carbon disulfude are produced, 4 x n(CS2) = 4 x 0.762 = 3.048moles of carbon monoxide is formed.

hope this helps:-)

Answer 2

Multiply the number of moles given by the ratio of coefficients in the balanced chemical equation. For example, for a), you are given the number of moles of carbon (6.30) and you are asked about carbon disulfide. The coefficient of carbon is 5 and the coefficient of carbon disulfide is 1. So the number of moles of carbon disulfide is 6.30*(1/5) = 1.26. 1.26 moles of carbon disulfide are formed. Use the same procedure to solve b).
