for each of the following acid-base reactions calculate the mass (in grams) of each acid necessary to completely react with and neutralize 4.85g of the base solution
1)2HNO3(aq)+ Ca(OH)2 (aq)> 2h20(l)+ Ca(NO3)2
2) H2SO4(aq)+ 2KOH(aq)---> 2H2O(l)+ K2SO4

    a. Write and balance the equation which you have.
    b. mols base Ca(OH)2 = grams/molar mass = ?
    c. Using the coefficients in the balanced equation, convert mols base to mols acid.
    d. Now convert mols acid to grams = mols acid x molar mass acid.
