Answer to Question #264633 in General Chemistry for eggnog

Question

. A balloon has a volume of 4.0 L when at sea level (1.0 atm) at a room temperature of 28 degrees Celsius. What will be its

volume when inflated with the same amount of gas at an elevation where the atmospheric pressure is 700 mm Hg at 28

degrees Celsius?

Answer 1

Since the number of moles n and temperature are constant, Boyle's law will apply.

Convert 1atm to mmHg.

$1atm=760mmHg$

$P_{1}V_{1}=P_{2}V_{2}$

$760×4=x×700$

$X=\frac{760×4}{700}=4.343$ L
