Question

molecular mass of 1 co2 2
ch4 3 h2o​

Answer 1

Answer:

1) Atomic mass of C = 12u

Atomic mass of O = 16u

Atomic mass of CO2 = 12 + 16 × 2

=> 44u

2) Atomic mass of C = 12u

Atomic mass of H = 1u

Atomic mass of CH4 = 12 + 1 × 4

=> 16u

3) Atomic mass of H = 1u

Atomic mass of O = 16u

Atomic mass of H2O = 1 × 2 + 16

=> 18u
