Question

How many O2 molecules can fit in a 48-L sealed jar?

Answer 1

Answer:

Note: Assume that the number of oxygen molecules is at STP. The volume of one mole of an ideal gas at STP is 22.414 L

\text{number of O₂ molecules = 48 L O₂} × \frac{\text{1 mol O₂}}{\text{22.414 L O₂}} × \frac{\text{6.022 × 10²³ O₂ molecules}}{\text{1 mol O₂}}number of O₂ molecules = 48 L O₂×

22.414 L O₂

1 mol O₂

×

1 mol O₂

6.022 × 10²³ O₂ molecules

\boxed{\text{number of O₂ molecules = 1.3 × 10²⁴ molecules}}

number of O₂ molecules = 1.3 × 10²⁴ molecules
