Question

139 D) 889 How many grams of CO2 will be produced if 45 g of C2H6 react with 32 grams of 02? The formula mass of C2H6 = 20 amu, H20 = 18 amu and 0, 32 amu 2 C2H6 +702-------> 4Co2 + 6 H20​

Answer 1

Answer:

Moleculer mass of H

2

=2×Atomic mass of H

=2×1μ=2μMoleculer mass of O

2

=2×Atomic mass of O

=2×16μ=32μ

Moleculer mass of Cl

2

=2×Atomic mass of Cl

=2×35.5μ=71μ

Moleculer mass of CO

2

=Atomic mass of C+Atomic mass of O

=(12+32)μ=44μ

Similarly,

Molecular mass of CH

4

12+(4×1)=12+4=16μ

Molecular mass of C

2

H

6

24+6=30μ

Molecular mass of NH

3

14+3=17μ

Molecular mass of CH

3

OH

12+3+16+1=32μ
