Explanation:
STP means standard temperature and pressure where values are as follows.
T = 273.15 K, P = 1 atm
According to ideal gas equation, PV = nRT. Since, it is given that mass is 48.3 g and we have to find the volume as follows.
n = [tex]\frac{mass}{\text{molar mass}}[/tex]
So, PV = nRT
V = [tex]\frac{mass}{\text{molar mass}} \times \frac{RT}{P}[/tex]
= [tex]\frac{48.3 g}{28 g/mol} \times \frac{0.0821 L atm/mol K \times 273.15 K}{1 atm}[/tex] (molar mass of CO = 28 g/mol)
= 38.68 L
Thus, we can conclude that volume of 48.3 g of carbon monoxide at STP is 38.68 L.
