A sample of potassium nitrate is collected in a 1500 mL flask. The pressure of the gas in the flask is 2.2 atm and the temperature is recorded to be 346.7K. How many molecules of O2 gas were produced? R=0.0821 atm L/mol K, K = 8.315 J/mol K, NA= 6.022 x1023 molecules/mol, k= 1.381 x 10-23 J/K, 1000.0 mL = 1.0 L. (Points : 20)
A) 6.892 x 1020 molecules
B) 6.022 x 1023 molecules
C) 3.473 x 1021 molecules
D) 5.182 x 1022 molecules
E) 1.234 x 1024 molecules
