two containers a and b are filled with 4 g of hydrogen gas and 32 g of oxygen gas respectively which of the two containers have more moles

1 answer

To determine which container has more moles, we need to calculate the number of moles in each container.

The number of moles can be calculated using the formula:

Number of moles = mass (in grams) / molar mass (in grams per mole)

The molar mass of hydrogen gas (H2) is 2 g/mol, and the molar mass of oxygen gas (O2) is 32 g/mol.

Container A (hydrogen gas):
Number of moles = 4 g / 2 g/mol = 2 moles

Container B (oxygen gas):
Number of moles = 32 g / 32 g/mol = 1 mole

Therefore, container A (filled with 4 g of hydrogen gas) has more moles than container B (filled with 32 g of oxygen gas).
