The weight of the body is equal to the force of gravity: P = F = m * g. The force of gravity (acceleration of gravity) is a constant value and, in this case, it is indicated in the condition g = 9.8 m / s ^ 2. Since we know the weight, as well as the acceleration g, from the formula P = mg we can express the mass m: m = P / g = 803.6 / 9.8 = 82 kg.
