Summary Question #1. A 2.50-g sample of impure sodium acetate was heated in the presence of
excess sodium hydroxide, producing methane gas and solid sodium carbonate. A volume of 415
mL of gas was collected over water at 27 °C and 742 torr.
a. What is the balanced chemical equation for the reaction?
b. How many grams of methane were produced, knowing that the vapor pressure of water at 27
°C is 27.8 torr?
c. How many grams of sodium acetate are required to produce this quantity of methane?
d. What is the precent pure sodium acetate in the impure sample?
