Question

According to the equation 2 KCIO 3(s) → 2 KCI(s) + 3 O 2(g)

A 3.00 g sample of KCIO 3 (122.5 g/mol) decomposes and the oxygen is collected over water at 24.0°C and 0.982 atm. What volume of oxygen gas will be collected, assuming 100% yield? P(H 2O) at 24.0°C = 22.38 Torr.

a. 911 mL

b. 301 mL

c. 605 mL

d. 1820 mL

e. 940 mL
