Answer to Question #322498 in General Chemistry for Erica Baghucan

Question

A 1.00 mol sample of gas at 25 °C and 1.0 atm has an initial volume of 22.4 L. Calculate the results of each change, assuming all the other conditions remain constant.

b. The volume is reduced to 275 mL. What is the pressure in millimeters of mercury

Answer 1

a. PV = nRT

1.0 atm × 22.4 L = 1.00 mol × 0.082 L atm / K mol × (25 + 273) K

b. P × 0.275 L = 1.00 mol × 0.082 L atm / K mol × (25 + 273) K

P = 88.86 atm

1 atm - 760 mm Hg

88.86 atm - x mm Hg

x = 67 532 mm Hg
