Answer:
0.0611 mol
Explanation:
Use equation:
PV = nRT
Questions tells us that the volume is 13.7 L
The pressure at STP is 1 atm
The temperature at STP is 273 K
The gas constant is 0.0821 atm L [tex]mol^{-1}[/tex] [tex]K^{-1}[/tex]
Rearranged to give us n:
n = PV / RT
n = (1 atm) (13.7 L) / (0.0821 atm L [tex]mol^{-1}[/tex] [tex]K^{-1}[/tex]) (273 K)
n = 0.0611 mol (3 sig figs)
