2. Calculate the mass of white solid CaCO3 that forms when 98ml of a 0.1M Ca(NO3)2 solution is mixed with 54ml of a 2.5M Na2CO3 solution.

3. Aluminum metal react with an excess HCl solution to produce aluminum cloride and hydrogen gas. If 46g of aluminum is reacted, what mass of hydrogen is produced?
