Question

when you burn 2 L of propane (C3H8) at stp , you find 5.6L of carbon dioxide has been produced what is the percent yeild

Answer 1

Answer:

93%

Explanation:

First write the balanced reaction

C3H8 + 5O2 --> 3CO2 +4H2O

2nd, find the theoretical yield

2L C3H8 (1mol/22.4L) (3 mol CO2/1 molC3H8) (22.4 L/ 1mol) = 6L

3rd, Find percent yield

%yield = (actual / theoretical) x100 = (5.7/6) x 100 = 93%
