In the laboratory a student finds that it takes 169 J to increase the temperature of 14.3 g of gaseous oxygen from 22.9 to 36.6 °C.

Answer 1

Is this part of a heat capacity question?

14.3 g O₂ × 1 mol/32 g = 0.4469 mol O₂

ΔT = 36.6 – 29.9 = 13.7°

The experimental molar heat capacity = (169 J)/[(0.4469 mol)(13.7)] = 27.60 J/mol-K
