Good Day

Problem:

what volume in L is occupied by 3.5 moles of co2 at STP

Given Data:

CO₂  amount in moles =  3.5 moles

Volume at STP = ? unknown

Solution:

Note: every one mole of any gas will occupy a volume of 22.4 L at STP.

We can have a conversion factor 22.4 L per 1 mole.

• Volume at STP = 3.5 moles  times the conversion factor.

3.5 mol × 22.4 L/1 mol =   78.4 L   (cancel the unit mol)

Answer:

3.5 moles of CO₂ will occupy a volume of 78.4 L at STP
