Answer #1

1) According to the reaction,

1 mole Al2S3 require 6 mole H2O

150 g Al2S3 require 108 g H2O

30 g Al2S3 require 108×30/150 g H2O

= 21.6 g H2O

Since we have only 20 g H2O thus, H2O is limiting reagent.

According to the reaction,

6 mole H2O give 3 mole H2S

108 g H2O give 3×34 = 102 g H2S

20 g H2O give 102×20/108 g H2S

= 18.89 g H2S
