Pressure versus temperature graph of an ideal gas is shown in figure. Density of the gas at point A is `rho_(0)`. Density at B will be

Explanation

`rho=(PM)/(RT)` or `rhoprop(P)/(T)`
`((P)/(T))_(A)=(P_(0))/(T_(0))` and `((P)/(T))_(B)=((3)/(2))(P_(0))/(T_(0))`
`((P)/(T))_(B)=(3)/(2)rho_(A)=(3)/(2)rho_(0)`
