## Lena772 one year ago Calculate the theoretical mass (in grams) of Sodium Sulfate produced using only the volume and molarity of Sulfuric Acid. Calculate the theoretical mass (in grams) of Sodium Sulfate produced using only the mass of Sodium Carbonate. What is the theoretical yield (in grams) of Sodium Sulfate? What mass (in grams) of the excess reactant is left over after the reaction?

1. Lena772

$H_{2}SO_{4}+Na_{2}CO_{3} \rightarrow H_{2}CO_{3} + Na_{2}SO_{4}$

Alright this is molarity question

3. anonymous

First off this is a double displacement question and I assume you know it.

4. Lena772

M= moles solute/L of solution moles solute= M*L m=4.9M*0.00698L =0.034202*105.99 g/ 1 mol = 3.6 mol However, I get that this is incorrect

5. Lena772

That should say 3.6g not mol.

This is a very simple question. You ask your periodic table "hey what's up man tell me what your molar mass label has to say and I'll add them up happy to the kingdom come"

7. anonymous

Oh shiz I didn't note "using only the mass for the reactant" ok

8. anonymous

You do the happy stoichometry

9. Lena772

Do you see where I went wrong?

10. anonymous

Why don't you just use the stoichiometry ratio?

11. anonymous

I recommend stoichoimetry for the sake of simplicity because it's easier

12. anonymous

@Nnesha what's your take on this?

13. Lena772

I don't know what you mean by the stoichiometry ratio.

14. anonymous

I am gonna give you the kingdom come so the ratio between sulfuric acid used and sodium sulfate used is 1:1 meaning that every mole of sulfuric acid results in one mole of sodium sulfate. So find the overall gram of sodium sulfate by looking at periodic table and add them together.

15. anonymous

for 1 mole of reactant results in 1 mole of product.

16. anonymous

pretty simple isn't it?

17. anonymous

@empty if you could elaborate what I mean that's great

18. anonymous

that dude got scared off

19. anonymous

ok I am here with you no worries

20. anonymous

but I am really sleepy right now vote on my thread

21. Lena772

Add what together? I don't understand.

22. anonymous

@empty pitch in dude don't be the spectator ion
