Which of following flasks has higher pressure ,
10.0 L containing 56.2 g Argon at 303 K

Explanation

Volume of Ar =10.0 L
Temperture =303 K
Mass of Ar =56.2 g
No. of Molesof Ar `=("Mass")/("Molar mass")=(56.2)/(40)`
`=1.405` moles
According to ideal gas eqation
`PV=nRT`
`P=(n)/(V)RT=(1.405xx0.0821xx303)/(10)`
`=3.765 atm`
