One litre sample of a gas having density `1.20 kg m^(-3)` at 1 atm and `0^(@)C` was compressed to `500` atm resulting a volume `4cm` in violation of Boyle's law The final density of the gas is .

Options

A. `400 kg cm^(-3)`
B. `300 kg cm^(-3)`
C. `200 kg cm^(-3)`
D. `100 kg cm^(-3)`

Answer

B

Explanation

Wt of 1 liter gas `= 1.20 xx 1.0 xx 10^(-3) kg`
` =1.2 xx 10^(-3) g`
Now density ` =(1.2 xx10^(-3))/(4.0 xx10^(-6)) =300 kg m^(-3)` .
