Question

What is the theoretical yield of Na2SO4, in grams?

Answer 1

@ryanwhite499 @Hoslos @felipecasal

Answer 2

what do you think it is..?

Answer 3

Hold on I'll be back

Answer 4

Yield, you mean molecular mass?

Answer 5

@Hoslos : The theoretical yield is the amount predicted by a stoichiometric calculation based on the number of moles of all reactants present.

Answer 6

Exactly. I asked that because I feel there is lack of information. At least we should hae had the amount of moles reacted in a reaction or something. The statement looks very vague.

Answer 7

the equation is: H2SO4+2NaOH-> 2H2O+Na2SO4

Answer 8

This is math @boricua5

Answer 9

no, its chemistry

Answer 10

Oh ok. I thought you had to plug the numbers in and stuff

Answer 11

Yes, you deal with numbers @ryanwhite499 , but this is stoichiometry, part of chemistry responsible for calculations.

Answer 12

I know @Hoslos. I'm still trying to figure this out. I thought this was a worded math problem at first.

Answer 13

@boricua5 , I think I need more information, like what amoun reacted, because if you simply give me the reaction, the yield would obviously be 100%, would not be?

Answer 14

Ok.

Answer 15

the limiting reactant is 10.8g of Na2SO4

Answer 16

Ok. Now we are talking.
Using your periodic table to find the molecular mass of Na2SO4 is (23*2)+32+(16*4)= 142g.
Using ratio of the obtained amount to the expected one is (10.8:142)*100= 7.6%
