Question

S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O In the above equation how many grams of water can be made when 3 grams of HNO3 are consumed?

Answer 1

6.2

Step-by-step explanation:

Based on stoichiometry HNO3 to H2O is 6:2

Use 9 grams to find the moles of HNO3

9 grams/63g/mol=0.143 moles of HNO3

HNO3:H2O

6:2

0.143*2/6=0.048

H2O moles is 0.048moles

Mass of water =0.048moles*18g/mol=0.864g

To the nearest tenth=0.9grams
