A sample of gas occurs 9.0mL at a pressure of 500mmHg. A new volume of the same sample is at 750mmHg. Use two significant figures in answer on volume.

V₂ = 6.0 mL

Explanation:

Given dа ta:

Initial volume = 9.0 mL

Initial pressure = 500 mmHg

Final volume = ?

Final pressure = 750 mmHg

Solution:

According to Boyle's Law

P₁V₁ = P₂V₂

V₂ = P₁V₁ / P₂

V₂ = 500 mmHg * 9.0 mL / 750 mmHg

V₂ = 4500 mmHg. mL / 750 mmHg

V₂ = 6.0 mL
