Chapter 7.8, Problem 7.63PP

Nitrogen dioxide and water react to produce nitric acid, ${\text{HNO}}_{\text{3}}$ , and nitrogen oxide.
${\text{3NO}}_{\text{2}}\left(g\right){\text{+H}}_{\text{2}}\text{O}\left(l\right)\to {\text{2HNO}}_{\text{3}}\left(aq\right){\text{+ NO}}_{\text{2}}\left(g\right)$

a. How many grams of ${\text{H}}_{\text{2}}\text{O}$ are needed to react with 28.0 g of ${\text{NO}}_{\text{2}}$ ?
b. How many grams of NO are produced from 15.8 g of ${\text{H}}_{\text{2}}\text{O}$ ?
c. How many grams of ${\text{HNO}}_{\text{3}}$ are produced from 8.25 g of ${\text{NO}}_{\text{2}}$ ?
