[quanative chemistry] Barrium carbonate decmposition
« on: May 19, 2007, 07:12:56 AM »
Ba = 137 O = 16 C = 12

Hi I have the question

What mass of barium oxide AND what volume of carbon dioxide would be produced if 20g of barium carbonate was thermally dcomposed?

I got 15.53g for the BaO bu for the CO2 im unsure. I know that any gas at room temperature occupies a volume of 24dm³, so what do I do?

Thanks

Can you find the number of moles of CO2 produced?  Just multiply the number of moles of CO2 by 24dm3/mole to get the volume of CO2.
