Answer:

40.0L is the volume the CO occupy

Step-by-step explanation:

To solve this question we must assume the gas is at STP. To find the volume of a gas using the moles, temperature and pressure of the gas we have to use:

PV = nRT

V = nRT / P

Where V is volume in liters

n are moles of the gas -Molar mass CO: 28g/mol-

50.0g * (1mol / 28g) = 1.786 moles CO

R is gas constant = 0.082atmL/molK

T is absolute temperature = 273.15K at STP

P is pressure = 1atm at STP

Replacing:

V = 1.786moles*0.082atmL/molK*273.15K / 1atm

V = 40.0L is the volume the CO occupy
