Question

A car emits 411g of carbon dioxide gas in 1 mile of driving. How many liters of carbon dioxide emit at STP?

Answer 1

The volume of Carbon dioxide at STP = 209.22 L

Further explanation

Given

411g of Carbon dioxide gas

Required

The volume of Carbon dioxide

Solution

mol of Carbon dioxide :

= mass : MW CO₂

= 411 g : 44 g/mol

= 9.34

Conditions at T 0 ° C and P 1 atm are stated by STP (Standard Temperature and Pressure). At STP, Vm is 22.4 liters/mol.

So for 9.34 mol :

= 9.34 x 22.4 L

= 209.22 L
