Question

A 10 L flask contains a gaseous mixture of $COandCO_{2}$at a total pressure of 2 atm and 298 K. If $0.20$mole of CO is present, find its partial pressure.

• A. $0.49$atm
• B. $1.51$atm
• C. 1 atm
• D. 2 atm

Answer 1

Answer: (A)

$0.49$atm

Answer 2

: $P = \frac{nRT}{V} = \frac{0.20 \times 0.0821 \times 298}{10} = 0.49atm$
