Answer to Question #333683 in General Chemistry for Shaila

Question

A 0.25 moles neon is at 256 mmHg and at temperature of 35°C. What is the volume? (1 atm = 760 mmHg)

Answer 1

PV = nRT

R = 0.082 atm*L/mol*K

P = 256 mmHg = 0.34 atm

T = 35°C = 308.15 K

V = nRT/P

V = (0.25 moles * 0.082 atm*L/mol*K * 308.15 K)/0.34 atm = 18.58 L
