Q98227


Soluton :

Given; "V_i=9.20L" ";T_i=T_f=294K; P_i=0.959atm; P_f=1.15atm"

To find: "V_f"


As number of moles stays constant;

"PV=nRT \\implies PV\/T=constant"

"\\therefore P_iV_i\/T_i=P_fV_f\/T_f"

"\\implies V_f=(P_iV_iT_f)\/(T_iP_f)"

"=(0.959*9.2*294)\/(294*1.15)"

"=7.672L" (Answer)


Thus, newly occupied volume of "N_2" gas sample is "7.672L"
