When 300 J of heat given to an ideal gas with C_ p = 7 2 R its temperature raises from 20^ C to 50^ C keeping its volume constant. If n is the number of moles of the gas, then what is the value of 100n ? ( R =8.314 ~J / mol . K )

Correct answer

0

Step-by-step solution

Given: C_P = 7 2 R , so C_V = C_P - R = 5 2 R Q = nC_V T (constant volume) 300 = n 5 2 8.314 30 n = 0.48 mol 100n = 48
