How many moles are there in 132g of CO2? How many dm3 would this be

First, calculate one mole of CO2. Go to the periodic table, and we see that the atomic mass of Carbon is 12 and Oxygen is 16. Atomic mass is also the grams of 1 mole.

So, 1 mole of Carbon is 12 grams, and 1 mole of Oxygen is 16 grams. We have 2 oxygen here, so one mole of O2 is 32 grams, add that to carbon and we get 44 grams in a mole of CO2.

Take 132 and divide that by 44 and we get 3. SO there are 3 moles of CO2.

Now for the Volume:

At standard temperature and pressure, ideal gasses will fill 22.4 liters for one mole. So, 3 moles of CO2 fill out 65.2 liters.

Convert liters to dm3, and we get 65.2 dm3
