MCQ

Problem:

10 g of hydrogen and 64 g of oxygen were filled in a steel vessel and exploded. Amount of water produced in this reaction will be

(a) 1 mol 

(b) 2 mol 

(c) 3 mol 

(d) 4 mol


Solution:

2H2 + O2 rightwards arrow2H2O
4 g     32 g    2 moles

4g of H2 require 32 g of O2.

So, 10 g of H2 will require = 32 over 4 cross times 10 = 80 g

In the question, as 10 g of H2 is to react with 64 g of O2

So, O2 will completely consumed and will act as limiting reagent.
32 g of O2 gives H2O = 2 mol

64 g of O2 gives H2O = 2 over 32 cross times 64 = 4 mol

Option (d) is correct
