Mole-Mass problems- be sure to balance first
1. In photosynthesis, plant use energy from the sun to produce glucose, C6H12O6 and oxygen from the reaction
of the carbon dioxide and water. CO2 + H2O C6H12O6 + O2 What mass, in grams, of glucose and oxygen are
produced when 3.25 mole of water react.
2. When magnesium burns in air, it combines with oxygen to form magnesium oxide. Mg + O2  MgO How
many grams of magnesium oxide is produced and oxygen is formed from 0.25 mol magnesium?
3. Chlorine gas can be produced by passing an electric current through a concentrated solution of sodium
chloride and water. Sodium hydroxide and hydrogen gas are also products. NaCl + H2O  Cl2 + NaOH + H2
How many grams of the three products can be produced from 0.175 mol of sodium chloride?
4. Tin II fluoride, is used in some toothpastes. It is made by the reaction of tin with hydrofluoric acid. Sn + HF
 SnF2 + H2 How many grams of tin II fluoride and hydrogen gas are produce from 0.325 mol of Tin?
