Molar mass
g/mol

3. What is the molar mass of hydrogen?
2 g/mol

4. What is the molar mass of sodium chloride?
58.45 g/mol

5. If you have 8 g of hydrogen how many moles is this?
4 mol H2

6. If you have 0.50 mol of carbon dioxide, how many grams is that?
22 g CO2

7. What is the flight number from Mole Town to DC?

15. Stoichiometry
Date:

16. Stoichiometry
The calculation of the quantities of reactants and products involved in a chemical reaction.
Using Mole Town to convert between amounts of reactants and products.
Just like what we’ve done before, with one additional step.

17. Steps to Stoichiometry
Into Moles
Mole to mole ratio
Out of Moles
Use mole town to get into and out of moles, use the ratio of coefficients from the balanced equation to get mole ratio

18. If 4 mole of O2 are reacted with excess H2, how many moles of H2O will be produced? 2 H2 + O2  2 H2O

19. To produce 22. 4 L of NH3, how many liters of H2 are needed
To produce 22.4 L of NH3, how many liters of H2 are needed? N2 + 3 H2  2 NH3

20. To produce 44. 8 L of N2, how many liters of H2 are needed
To produce 44.8 L of N2, how many liters of H2 are needed? N2 + 3 H2  2 NH3

21. Practice Time!
Using dry erase markers and whiteboards, complete the worksheet in the sheet protector. Write answers on sheet protector – they can be wiped off! 
Show your leader when complete.
Once group is done – work on stoichiometry practice.
