Back to Mole Town! Agenda Review Mole Town map. Intro stoichiometry. Practice, practice, practice!

What is the flight number from Mole Town to Mtn of Mass? Molar mass g/mol

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

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

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

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

What is the flight number from Mole Town to DC? 6.02*1023 RP/mol

If you have 2.00 mol of H2, how many molecules is this? 1.20 *1024 MC H2

If you have 3.01*1023 atoms Na, how many moles is that? 0.500 moles Na

What is the flight number between Mole Town and the Valley? 22.4 L/mol

Stoichiometry Date:

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.

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

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

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

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

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.
