Question

Answer 1

Answer #1

Balanced equation is,

C₂H₅OH + 3 O₂ -----------> 2 CO₂ + 3 H₂O

From the balanced equation

1 mol (46 g.) of ethyl alcohol produces 2 mol of CO₂

The, 57.3 g. of ethyl alcohol produces 2 * 57.3 / 46 = 2.49 mol of CO₂

Assuming ideal behavior,

Ideal gas equation, P V = n R T
V = 2.49 * 0.0821 * 305.15 / 1.62

V = 38.5 L
