Question

What is the ratio by mass of combining elements in H20, CO2 and NH3 ?and explain it
​

Answer 1

Answer:

NH3 = atomic mass of N=14

molecular mass of H = (1*3)=3

ratio of mass of NH3= N:H3

= 14:3

• one Nitrogen atom combines with three Hydrogen atoms and molecular weight of the compound formed is 17.

• Formula of the compound formed in the given ratio and calulated molecular weight is NH3 (ammonia).

• Following equation shows the formation of ammonia molecule from Nitrogen and Hydrogen. N2 + 3H,+2NH3

Hope this will help you ☺️♥️

Answer 2

In H2O,

Mass of H2= 2×1=2

Mass of O= 16

Ratio of H2 and O= 2:16=1:8

In CO2,

Mass of C= 12

Mass of O2= 16×2= 32

Ratio of C and O2= 12:32=3:8

In NH3,

Mass of N= 14

Mass of H3= 3×1=3

Ratio of N and H3= 14:3
