How many moles of gas are present in 57.20 L of argon at a pressure of 1 atm and a temperature of 0°C?
1 answer:
Answer:
n= 2.55 moles
Explanation:
Using the formula of ideal gas law:
PV = nRT
nRT=PV
n= PV/RT
n= number of moles
R= Avogadro constant = 0.0821
T= Temperature in K => ºC + 273.15 K
V= volume in L
P= pressure in atm
n= (1 atm)(57.20 L) / (0.0821)(237.15 K)
n= 2.50 moles
