The question states: Solid sodium reacts violently with water, producing heat, hydrogen gas, and sodium hydroxide. How many molecules of hydrogen gas are formed when 87g of sodium are added to water?
2Na + 2H2O ----> 2NaOH + H2
Do I convert the grams of sodium to moles and then the moles of hydrogen to molecules? I don't know how to do this, please help!

stoichiometry. start with 87 g Na
87 g Na x (1mole Na/ 23 g Na) x (1 Mole H2/2 mole Na)(6.02x10^23 molecules H2/1 mole)=
1.14x10^24 molecules of H2
87 g Na x (1mole Na/ 23 g Na) x (1 Mole H2/2 mole Na)(6.02x10^23 molecules H2/1 mole)=
1.14x10^24 molecules of H2
