2. The number of mole of 250 cm³ of CO at STP is 0.01 mole

Volume of gas at STP

At standard temperature and pressure (STP),

1 mole of gas = 22.4 dm³ = 22400 cm³

1. How to determine the mole of 54.5 dm³ of CH₄

At standard temperature and pressure (STP),

22.4 dm³ = 1 mole of CH₄

Therefore,

54.5 dm³ = (54.5 dm³ × 1 mole) / 22.4 dm³

54.5 dm³ = 2.43 moles of CH₄

2. How to determine the mole of 250 cm³ of CO

At standard temperature and pressure STP,

22400 cm³ = 1 mole of CO

Therefore,

250 cm³ = (250 cm³ × 1 mole) / 22400 cm³

250 cm³ =0.01 mole of CO
