Answer to Question #207434 in Chemistry for Deliciann Balkarra

Question

A balloon takes up 10 L of volume at 300 K and a pressure of 3.5 atm. At what pressure will the balloon have a volume of 30 L and a temperature of 4.2 atm?

Answer 1

pV = nRT

R = 0.082 L atm K⁻¹ mol⁻¹

3.5 x 10 = n x 0.082 x 300

n = (3.5 x 10) / (0.082 x 300) = 1.4 mol

4.2 x 30 = 1.4 x 0.082 x T

T = (4.2 x 30) / (1.4 x 0.082) = 1097 K
