Question

What is the volume of 3.5 moles of chlorine gas at a standard temperature and pressure

Answer 1

Hey there!:

1 mole Cl --------------- 22.4 L (at STP )

3.5 moles Cl ---------- ( ?? Volume of Chlorine )

Volume of chlorine = 3.5 * 22.4 / 1

Volume of chlorine = 78.4 / 1

Volume of chlorine = 78.4 L

Hope that helps!

Answer 2

78.4 L

Explanation:

1 atm is the standard pressure and 273K is the standard temperature.

22.4 L is the standard molar volume of a gas that it occupies at STP.

At STP (standard temperature and pressure), one mole of a gas has a volume of 22.4L.

3.5 mole x
`(22.4 L)/(1 mole)` = 78.4 L
