caculate the mass of agcl precipitated when 0.1g of nacl and 0.1g of agno3 are mixed in solution

Answer 1

Convert 0.1 g NaCl and 0.1 g AgNO3 (note: nacl and agno3 don't mean a thing--don't be so lazy in chemistry that you can't punch the CAPS key). Here is a worked example of a stoichiometry problem. Print this out--it will solve 99.9% of the stoichiometry problems you are likely to encounter.
