answer

The molar heat capacities of substances varies with temperature. The general function for determining the molar heat capacity is given below; Cp = ( a + b T + c T 2 )R . In case of a gas where a = 3.245, b = 7.108 x10 ^-4 K ^-1 , and c = -4.06 x10^ -8 K ^-2 for temperatures in the range of 300 Kelvins to 1,500 Kelvins. What is the heat capacity (in Joules per Kelvin per mole) of this gas at 1,500 kelvins? NOTE: Express answer in THREE SIGNIFICANT FIGURES.
