Question

2g of O2 at stp occupies the volume? ​

Answer 1

Answer:

Assuming that the gas is at standard temperature and pressure (STP), one mole of any gas occupies 22.4 L . This means the number of moles of O2 is 222.4=0.089 mol .

Explanation:

Answer 2

Answer:

1.4 L

Explanation:

Molecular Volume of a gas at STP = 22.4 L

Given mass of $O_2$ = 2g

⇒ No. of moles of  $O_2$ = 2/32= 0.0625 moles

∴ Volume occupied by 2 g of  $O_2$  = 0.0625 × 22.4 L = 1.4 L
