solid sodium reacts violently with water, producing heat, hydrogen gas, and sodium hydroxide. how many molecules of hydrogen gas are formed when 48.7 g of sodium are added to water?
2Na + 2H2O ------> 2NaOH + H2

1. Samantha

convert grams to moles then use the equatino to do moles of Na to moles of H2O then convert moles of H2O to molecules by using avogadros number (6.022e23) I believe

Samantha has a good plan.
