Hi Sydney R

First make sure you have balanced equations, if so then just use the moles in the equation as ratios to solve for unknown amount

__1.)__**S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O**

**Says that 6 moles of Nitric Acid make one mole of Sulfuric acid you can also interpret that as for each mole of Sulfuric acid you need 6 moles of Nitric Acid**

**1 mole Sulfuric Acid/6 moles of Nitric Acid**

**1 mole Sulfuric Acid/6 moles of Nitric Acid = x moles of Sulfuric Acid/56 moles of Nitric Acid**

**Just cross multiply to find x**

**I get 9.3 moles of Sulfuric Acid**

__2.)__**S + 6 HNO3 --> H2SO4 + 6 NO2 + 2 H2O**

**Says 6 moles of Nitric Acid are consumed to yield 2 moles of Water, you can also state that**

**2 moles of Water are made when 6 moles of Nitric Acid are consumed**

**2 moles of Water/6 moles of Nitric Acid**

**2 moles of Water/6 moles of Nitric Acid = x moles of Water/ 57 moles of Nitric Acid**

**Just cross multiply to solve for x**

**I get 171 moles of Water**

I hope this helps just send me a message if you have any questions.
