Question

Reference the following attachment

Answer 1

The number of molecules of gases in each of the 3 vessels is the same.

Number of moles

The first vessel contains 2g of $H_2$ gas:

Number of molecules in 2 g = 2/2 = 1 mole

The second vessel contains 32 g of $O_2$ gas:

Number of molecules = 32/32 = 1 mole

The third vessel contains 44 g of $CO_2$ gas:

Number of molecules = 44/44 = 1 mole

Thus, the 3 vessels contain the same number of moles of gases.
