The volume of a fixed mass of gas at 760 mmHg is 1500 cm^3. what is the pressure if the volume is reduced to 1000 cm^3 at constant temperature?

#"1140 mmHg"#

Explanation:

Boyle’s Law: The pressure exerted by a given mass of an ideal gas is inversely proportional to the volume it occupies if the temperature and amount of gas remain unchanged within a closed system.

Mathematically,

#"P" ∝ 1/"V"#

#"P"_1"V"_1 = "P"_2"V"_2#

#"P"_2 = ("P"_1"V"_1)/"V"_2 = (760\ "mmHg" × 1500 cancel("cm"^3))/(1000 cancel("cm"^3)) = "1140 mmHg"#
