The equation of state for n moles of an idea gas is PV=nRT. Where R is the universal contant. The dimension of R is

Answer»

`M^(0)LT^(-2)K^(-1)mol^(-1)`
`ML^(2)T^(-2)K^(-1)mol^(-1)`
`M^(0)L^(2)T^(-2)K^(-1)mol^(-1)`
`ML^(-2)T^(-2)K^(-1)mol^(-1)`

Solution :Universal GAS constant, `R=(PV)/(nT)=([ML^(-1)T^(-2)][L^(3)])/([mol][K])`
Dimensionally, `ML^(2)T^(-2)K^(-1)mol^(-1)`
