Answer:

What causes environmental pollution is global warming and climate change
To find this you have to find the molar mass of CO2 which you can get on the periodic table, 12 + 16 + 16 = 44 g/mol
4.49 x 10^0 / 44 g/mol = .1020 mol CO2
1 mol = 6.022 x 10^23 molecules (avogadros number)
so .1020 mol x 6.022 x 10^23 =
6.14 x 10 ^22 molecules CO2
