OK. So they want me to do molarity equations, yet they give no supporting evidence on HOW to do them.. Here they are:

1) What mass of each product results in 750. mL of 6.00 M H₃PO₄ reacts according to the following equation?
2H₃PO₄+3Ca(OH)₂--->Ca₃(PO₄)₂+6H₂0

2) How many milliliters of 18.0 M H₂SO₄ are required to ract with 250. mL of 2.50 M Al(OH)₃ if the products are aluminum sulfate and water?

3) 75.0 g of an AGNO₃ solution reacts with enough Cu to produce 0.250 g of Ag by single replacement. What is the molarity of the initial AgNO₃ solution if Cu(NO₃)₂ is the other product?

I really only need the explanation for one, and then I should be able to figure the other two out. It's just that we have been sticking to specific molarity problems, and not placing them in with equations. Anyways, any help would be appreciated.
