Question

3. 2 g of oxygen and 0. 2 g of hydrogen

Answer 1

Answer:

The molecular weights of oxygen and hydrogen are 32 g/mol and 2 g/mol respectively.

The number of moles of oxygen =

32g/mol

3.2g

=0.1mol.

The number

0.2g

=0.1mol.

Total number of moles =0.1+0.1=0.2 moles.

Total pressure P=

V

nRT

=

1.12L

0.2moles×0.08206Latm/molK×273.15K

=4atm

Thus, the total pressure in atm of the gas mixture will be 4 atm.
