Answer:

0.76L is the pressure of CO at STP

Explanation:

To solve this question we must use combined gas law:

PV = nRT

Where P is the pressure of the gas (1atm at STP)

V is volume (Our incognite)

n are moles of the gas (0.950g * (1mol/28g) = 0.034 moles

R is gas constant (0.082atmL/molK)

T is absolute temperature (273.15K at STP)

V = nRT/P

V = 0.034mol*0.082atmL/molK*273.15K / 1atm

V = 0.76L is the pressure of CO at STP
