How many grams of calcium chloride will be produced when 31g of calcium carbonate are combined with 11 g of HCl?
I have 0.3097 moles of CaCO3
and 0.30169 moles of HCl...I get stuck at that point
Look at the equation:
each mole of CaCO3 produces one mole of CaCl2.
So, you will wind up with .3097 moles of CaCl2.
Convert that to grams, and you're done.
