Explanation / Answer

Multiple questions. Please split the rest of the questions.

1. moles of C = 2.5*2 = 5

moles of H = 2.5*6 = 15

moles of S = 2.5

moles of O = 2.5

2. A - Number of moles of water required = 2.35*2 = 4.70

B - mass produced = 5.22*74 = 386.28 g

C - mass of water reqd = (1.5/26)*2*18 = 2.0769 g
