Question

How many liters do 1.55 g of O2 occupy at STP?

Answer 1

The volume that is occupied by the given mass of the oxygen gas is 1.1L

What is the volume?

We know that the volume has to do with the space that is occupied by a gas. Now we know that from the Avogadro's law, the volume that is occupied by a gas is called the molar volume of the gas and it has a value of 22.4 L.

We now have;

Number of moles of the gas = 1.55 g/32 g/mol

= 0.048 moles

If 1 mole of the gas occupies 22.4 L

0.048 moles of the gas is going to occupy 0.048 moles * 22.4 L/1 mole

= 1.1 L
