Question

Solid sodium reacts violently with water, producing heat, hydrogen gas, and sodium hydroxide. How many molecules of hydrogen gas are formed when (46.3 g) 48.7 g of sodium are added to water? Show your work. Assume the sodium is limiting:
Na (s) + H2O (l) H2 (g) + NaOH (s)
Also if sodium is the limiting reactant, what does this indicate about H2O in this reaction?

Answer 1

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)
