Question

A laboratory experiment requires you to prepare a 1.30M solution of sodium carbonate. If the procedure requires 50ml of the solution how many grams of sodium carbonate are needed to prepare this solution A laboratory experiment requires you to prepare a 1.30M solution of sodium carbonate. If the procedure requires 50ml of the solution how many grams of sodium carbonate are needed to prepare this solution A laboratory experiment requires you to prepare a 1.30M solution of sodium carbonate. If the procedure requires 50ml of the solution how many grams of sodium carbonate are needed to prepare this solution

Explanation / Answer

number of moles = molarity * volume (lit)

number of moles of sodium carbonate = 1.3 M * 0.05lit = 0.065 moles

mass of sodium carbonate = 0.065 moles * 106 g/mole = 6.89 g
