4.	How many moles of NO can be produced by the reaction of 54.0g of Ag?

5.	How many grams of AgNO3 can be produced by recating completely 88.0g of Ag?

6.	State the number of grams of water that can be obtained by the reaction of 324g of Ag with 126g of HNO3

Here is a worked example. Just follow the steps. This will work all of the ones you posted except for 6. That is a limitiing reagent problem and you need to do that slightly differently.
