The density of neon will be minimum at

Options

A. STP
B. `0^(@)C, 2 atm`
C. `273^(@)C, 1 atm`
D. `273^(@)C, 2 atm`

Answer

C

Explanation

`PV = nRT`
`PV = (w)/(M) RT`
`(PM)/(RT) = d`
(A) `d = (1 atm xx M)/(R xx 273 K)`
(B) `d = (2 atm xx M)/(R xx 273 K)`
(C) `d = (1 atm xx M)/(R xx 546 K)`
(D) `d = (2 atm xx M)/(R xx 546 K)`
