Question

suppose 5.00g of sodium carbonate reacts completely with excess of hydrochloric acid. Show how to calculate the mass (g) of sodium chloride that would be formed.


Na2CO3 + 2HCl = 2NaCl + CO2 + H2O


What is the limiting reagent?

Answer 1

how many moles of sodium carbonate is in 5 grams? From the balanced equation, one gets twice that number of moles of sodium chloride. That number can be converted to grams of sodium chloride.
