What are the accepted values for the number of moles of NaCl that are produced from HCl and the following various amounts of grams of NaHCO3;

0.25 grams
0.5 grams
1 gram

Please Help!

  • chemistry -

    All of these are done alike. I'll do the first one.
    HCl + NaHCO3 ==> H2O + NaCl + CO2

    mols NaHCO3 = grams/molar mass = 0.25/84 = 0.00298.
    mols NaCl = mols NaHCO3 (from the 1:1 ratio in the balanced equation.)
    Therefore mols NaCl from 0.25 mols NaHCO3 = 0.0030 mols to two significant figures.
