1. Stoichiometry 5

2. Problem 13 Balance the Equation
What mass of H2SO4 is produced from the reaction of 6.58 grams of SO3 and 1.64 grams of H2O?????
SO3 + H2O  H2SO4
H2SO4+SO3  H2O

3. Correct!   
SO3 + H2O  H2SO4
1 Sulfur, 2 Hydrogen, 4 oxygen = 2 Hydrogen, 1 Sulfur, 4 Oxygen

4. Step 1 of Equation 1 6.58 g SO3 x __1 mol__ 80.86 g SO3
6.58 g SO3 x ___65 mols__
` g SO3
6.58 g SO3 x ____1 mol___
g SO3

5. Correct!
Good Job
Keep Up
The
Good
Work

6. Step 2 of Equation 1 1 mol 2 mols 1 mol x 265.17 g H2SO4

7. Excellent!  Congratulations! From now on…
If you get an answer correct, you will be forwarded to the next question

8. Step 3 of Equation 1 (6.58 + 98.08) (80.07) = 8.01 g H2SO4
(6.58 x 98.08)
(80.06) = 8.06 g H2SO4
(7.0 x 97.99)
(80.06) = g H2SO4

9. Equation 2 of Problem 13 Repeated Question
What mass of H2SO4 is produced from the reaction of 6.58 g of SO3 and 1.64 g of H2O?

10. Step 1 of Equation 2 1.64 g H2O x 1 mol 18.02 g H2O 1.64 g H2O x 1 mol

11. Step 2 of Equation 2 1 mol 1 mol 1 mol x 145.23 g H2SO4
2 mols
1 mol x g H2SO4
1 mol

12. Step 3 of Equation 2
8.9 g H2O
9.7 g H2O
4.2 g H2O

13. The Final Question
Which compound is the limiting factor???
SO3
H2SO4

14. Yeah, you are done!   

15. WRONG ANSWER!
