a.How many milliliters of 0.500 M Al(NO3)3 contains 229.00 g of the solute?

b.What mass of NO2 can be produced by the complete reaction of 42.00 g of ammonia with 104.00 g of oxygen:
4NH3 + 7O2 4NO2 + 6H2O
 
b.)
Step 1.Find the Limiting Reactant by setting up a mole ratio using the factor-label method. Like, if you used all 42.00 g of ammonia, how much oxygen would you need? Do you have enough oxygen? If you don't, then oxygen is your limiting reactant.
Step 2: Then, using the Limiting Reactant, set up a mole ratio to determine the grams of NO2 used. Factor-Label Method again.
