Consider following reactions:
Consider following reactions: The sum of molecular masses of gas A and B is ____________ u .
The sum of molecular masses of gas AA and BB is ____________ u.u .

Correct answer

46

Step-by-step solution

Gas ′A′'A' is hydrogen gas (H2)\left({H}_{2}\right) Molecular mass of {\text{H}_{2} = 2\text{u}
Gas ′B′'B' is carbon dioxide CO2{CO}_{2} .
Molecular mass of {\text{CO}_{2} = 44\text{u}
∴Sum=2+44=46u∴ \text{Sum} = 2 + 44 = 46\text{u}
