Calculating Mass of Sodium Chloride
Not what you're looking for?
Sodium chloride is obtained when sodium carbonates react with hydrochloric acid. The equation for the reaction is:
Na2CO3 = 2HCl --> 2NaCl + CO2 + H20
Calculate the mass of sodium chloride that can be obtained when 5 g of sodium carbonate is completely decomposed.
(RAM = C=12, 0 = 16, Na = 23)

By reading the coefficients in the reaction equation, we see that we get 2 moles of NaCl for each mole of sodium carbonate reacted. The first step we need to do is calculate the moles of sodium carbonate that we are going to react. To do this we need the molecular weight of sodium carbonate. It is calculated by summing up the atomic weights of the atoms which are in sodium carbonate. This is:
MW(Na2CO3) = 2*AW(Na) + ...
