Question

5000dm^3 of CO2 are absorbed by the leaves of an oak tree every day. How many moles and how Kg of CO2 is this?

Answer 1

n = V/Vm

Where

n is mol

V is volume

Vm is molar volue

So applying to the above equation, find the mols

n = 5000dm³/22.4dm³mol-¹

= 223.214mol of CO2

then apply the equation n=m/M where

m is mass

M is molar mass

therefore :

m = 223.214×44

= 9821.416g of CO2
