Activity 3: Mole to mole calculations:
A mole ratio is the ratio between the number of moles of any two species involved in a chemical
reaction. It is used to convert the number of moles of a substance to the corresponding number
of moles of another substance in a chemical reaction.
Like balancing chemical equation, making stoichiometric calculations requires practice. Solve the
following mole to mole calculations and write your solutions and answer on the space provided.
1. How many moles of oxygen (O2) will be produced from 6.2 moles of water (H2O)?
2H2 + O2 2H2O
2. How many moles of carbon dioxide (CO2) will be produced by complete reaction of 2 moles
of glucose (C6H12O6)
C6H12O6 + 6O2 6CO2 + 6H2O
3. How many moles of ammonia (NH3) can be produced from 8 moles of hydrogen (H2)
reacting with nitrogen.
3H3 +N2 2NH3
4. Given a balanced chemical reaction. A) Calculate the number of moles of potassium
dichromate (K2Cr2O7) that will react with 2 moles of potassium iodide (KI). B) calculate
the number of moles of iodine (I2) that will be produced from 2 moles of potassium iodide
(KI)
K2Cr2O7 + 6KI +7H2SO4 Cr2(SO4)3 + 4K2SO4 + 3I2 +7H2O
4
5. How many molecules of water (H2O) can be produced by reacting 0.010 moles of oxygen
with hydrogen?
2H2 + O2 2H2O
