Chapter 11, Problem 112CP

When heated, ${\text{KClO}}_{\text{3}}$ forms $\text{KCl}$ and ${\text{O}}_{\text{2}}$ . When a sample of ${\text{KClO}}_{\text{3}}$ is heated, 226 mL of gas with a pressure of 744 mmHg is collected over water at $\text{26 °C}\text{. At 26 °C}$ , the vapor pressure of water is 25 mmHg. (11.7, 11.8, 11.9)
   ${\text{2KClO}}_{\text{3}}\left(s\right)\stackrel{\Delta }{\to }\text{2KCl}\left(s\right){\text{ + 3O}}_{\text{2}}\left(g\right)$
a. What is the pressure, in millimeters of mercury, of the dry ${\text{O}}_{\text{2}}$ gas?
b. How many moles of ${\text{O}}_{\text{2}}$ were produced?
c. How many grams of ${\text{KClO}}_{\text{3}}$ were reacted?
