Question

2.85 L of CO_2 has a pressure of 625 mm Hg at 22.8 °C. What volume will it have at 75.0 °C and 825 mm Hg?

A) 2.54 L
B) 860. L
C) 07.10 L
D) 14.3 L

Answer 1

The volume will be 2.54 L at 75.0 °C and 825 mm Hg.

Step-by-step explanation:

To solve this problem, we can use the combined gas law, which states that PV/T = constant. We can rearrange the equation to solve for the final volume:

V2 = V1 * (P1/P2) * (T2/T1)

Substituting the given values:

V2 = 2.85 L * (625 mm Hg / 825 mm Hg) * (348 K / 295 K)

V2 = 2.54 L

Therefore, the volume will be 2.54 L at 75.0 °C and 825 mm Hg.
