Question

If 0. 750 l of argon at 1. 50 atm and 177°c and 0. 235 l of sulfur dioxide at 95. 0 kpa and 63. 0°c are added to a 1. 00-l flask and the temperature is adjusted to 25. 0°c, what is the resulting pressure in the flask?.

Answer 1

Answer:

Explanation: If 0.750 L of argon at 1.50 atm and 177oC...

P V = n R T

(1.50) (0.750) = n (0.08206) (443.15)

1.125 = n (36.36)

1.125 / 36.36 = n

0.031 mol Ar = n
