Is 1 Mole of BaSO4 Equal to 1 Gram?

[kara]

I obtained a net ionic equn' as follows

Ba +2 (aq) + SO4 2- (aq) ----> BaSO4 (s)

Now I need clarification for the following question and my answer to it.

What is the max amount of solid product that could be obtained by reacting one mole of each reactant?

I believe that b/c of the mole ratio being 1:1 between both reactants and the product, so the max amount of solid product would be 1 mol, or 1 g.

Is this reasonable to state?

Ba²⁺_(aq) + SO₄^2-_(aq) ----> BaSO_{4 (s)} is a one to one ratio (i.e. 1:1). So one mole of each reactant will produce one mole of the solid, if the reaction is 100% efficient. However, it will not produce one gram of the solid. Remember, the mole is not the same as mass. One mole of a substance contains 6.23 x 10²³ molecules of the substance but one gram of a substance can contain different numbers of moles.

Remember that: Molar Mass / M_r (Units: g mol^-1) = Mass / m (Units: g) / Moles / mol (Units mole)

So one mole of Carbon will have a mass of 12 grams but one mole of Hydrogen gas will have a mass of 2g.

So on the whole, what you were saying was true.

So was it true, or not ;)

kara: 1 mole, but not 1 gram.

Yer, yer... very funny... It was almost all true. It was just the little

, or 1g

that was not. So...

1 mole of BaSO₄ is approx. 233 grams. Happy?
