Best ResponseYou've already chosen the best response.11 mole of \(\sf CO_2\) has 12 g of carbon and \(2 \times 16\) g of oxygen, so how many moles of \(\sf CO_2\) will have 16 g of oxygen?

Best ResponseYou've already chosen the best response.21 mole of every substance has 6.02x10^23 particles. for starters. \[CO2\] has one carbon atom and two oxygen atoms now to figure this out we need to look at our periodic table of elements which shows us the molecular weight of each atom. for oxygen it's 16 amu for carbon it's 12 amu what's amu? that's our atomic mass unit, our unit for measuring how heavy our element is. we want our mass in grams because we're not dealing with just one simple atom; infact we're dealing with a mole, or 6.02x10^23 particles of those atoms, and when we take into account moles of substances only then our units will be in grams, that's what we want to work with. 1 mole of oxygen atoms = 16g 1 mole of carbon atoms = 12g now for our molecule we have CO2 so 1 mole of CO2 will have 1 mol Carbon atoms will have 2 mol of oxygen atoms. I think it's clear now what to do.
