Find the molar mass of:

NaNO3

Find the molar mass of:

Ca3(PO4)2

How many grams is 31 moles of NaCl?

How many moles is 7 grams of CO2?

Balance:

__ Fe + __H2O __ Fe3O4 + __ H2

Using this chemical equation:

_3_Fe + _4_H2O _1_Fe3O4 + _4_H2

What is the mole ratio of H2O to Fe3O4?

Using this chemical equation:

_3_Fe + _4_H2O _1_Fe3O4 + _4_H2

How many moles of Fe3O4 will you get if you start with 2.7 grams of Fe?

Using this chemical equation:

_3_Fe + _4_H2O _1_Fe3O4 + _4_H2

How many grams of H2 will you get if you start with 4 moles of H2O?

Using this chemical equation:

_3_Fe + _4_H2O _1_Fe3O4 + _4_H2

How many moles of Fe3O4 would be produced if you used 7 moles of Fe?

Using this chemical equation:

_3_Fe + _4_H2O _1_Fe3O4 + _4_H2

What is the molar mass of Fe3O4?

Using this chemical equation:

_3_Fe + _4_H2O _1_Fe3O4 + _4_H2

What is the sum of the coefficients?

Balance:

___ CaCO3 + ___ HCl

___ CaCl2 + ___ CO2 + ___ H2O

Using this chemical equation

CaCO3 + 2 HCl CaCl2 + CO2 + H2O

What is the sum of the coefficients? (Hint: It is already balanced!)

Write the formula for all 7 of the diatomic elements.
