Question

3) What is the pressure of a mixture of gases containing 0.90 mol of argon, 1.3 mol of oxygen and 0.75 mol of nitrogen when the volume and temperature are equal to 9.5 m3 and 298 K respectively?

Answer 1

PV = nRT

P= nRT/V

= 0.90 x 8.31 x 298/ 9.5
= 234.6Pa for Oxygen

Answer 2

do the same thing with argon and nitrogen and add them together

Answer 3
