Question

H2+1/2O2 GIVES H20 IN THE ABOVE REACTION WHAT IS THE VOLUME OF WATER VAPOUR AT STP. GIVEN THAT 4G OF H2 AND 32g OF O2? ​

Answer 1

32

2H

2

+O

2

→2H

2

O

Molecular mass of H

2

=2 g/mol

Molecular mass of O

2

=32 g/mol

From the balanced chemical equation,

2×2=4 g of hydrogen requires 32 g of Oxygen to react completely
