Question

44-8, Number of H2 molecules.​

Answer 1

Answer:

The number of moles can be calculated using the formula,

No.of moles = Weight of the substance/Molecular weight of the substance

Moles of CO2 = 44/44 = 1 mol.

Moles of O3 = 48/48 = 1 mol

Moles of H2 = 8/2 = 4 mol.

Moles of SO2 = 64/64 = 1 mol.

4 moles of H2, i.e. 4×6.023×1023 molecules.
