Question No. 7
In which of the given conditions of temperature and pressure will the density of nitrogen have the largest value?
A. 540 K and 2 atm
B. 273 K and 1 atm
C. 540 K and 3 atm
D. 273 K and 2 atm

Dear Student,

we can use the formula,
pv=nRTbut, Density d=mv thus, v=mdLet us consider, 1 mole of nitrogen is participationg in this reaction, thus the mass becomes 14 gnow substitute the values of pressure and temperature given in all the options and compare the value of densityd=pmnRTi) d=2x141x8.314x540=0.00623ii) d=1x141x8.314x273=0.00616iii) d=3x141x8.314x540=0.00935iv) d=2x141x8.314x273=0.0123If you compare all the values, option 4 has the maximum density.
Regards,
