Molar volume of gas at STP = 22.4 L/mol
Volume of Cl₂ at STP = (23.2 mol) × (22.4 L/mol) = 520 L (to 3 sig. fig.)
Volume of N₂ at STP = (4.6 mol) × (22.4 L/mol) = 100 L (to 2 sig. fig.)
Volume of He at STP = (3.2 mol) × (22.4 L/mol) = 72 L (to 2 sig. fig.)
Volume of CH₄ at STP = (29 mol) × (22.4 L/mol) = 650 L (to 2 sig. fig.)
Volume of Cl₂ at STP = (23.2 mol) × (22.4 L/mol) = 520 L (to 3 sig. fig.)
Volume of N₂ at STP = (4.6 mol) × (22.4 L/mol) = 100 L (to 2 sig. fig.)
Volume of He at STP = (3.2 mol) × (22.4 L/mol) = 72 L (to 2 sig. fig.)
Volume of CH₄ at STP = (29 mol) × (22.4 L/mol) = 650 L (to 2 sig. fig.)

23.2 mol Cl₂:
23.2 mol x 22.4L/mol = 22.4•23.2 L
the rest are the same, just change the numbes.
One mole of any ideal gas at STP has a volume of 22.4L
One mole of any ideal gas at RTP has a volume of 24L
STP = 0ºC and 1 ATM RTP = 25ºC and 1 ATM
23.2 mol x 22.4L/mol = 22.4•23.2 L
the rest are the same, just change the numbes.
