Question

When the pressure of a 38.9 L of Ammonia is changed from 939.9 torr to 527.9 torr, what is the resulting volume? Round your answer to 1-decimal place.

a) 22.1 L
b) 42.8 L
c) 56.7 L
d) 31.4 L

Answer 1

To find the resulting volume when the pressure of a given volume of ammonia changes, we can use Boyle's Law: P₁V₁ = P₂V₂. By plugging in the given values and rearranging the equation, we can calculate the resulting volume.

Step-by-step explanation:

To solve this problem, we can use Boyle's Law, which states that the pressure and volume of a gas are inversely proportional at constant temperature. By plugging in the given values, we can set up the equation: P₁V₁ = P₂V₂. Solving for V₂, we get V₂ = (P₁V₁) / P₂.

Plugging in the values, we have V₂ = (939.9 torr * 38.9 L) / 527.9 torr = 69.73 L. Rounding to 1 decimal place, the resulting volume is approximately 69.7 L (option e).
