The weight of a cardboard box with 50 chocolates is 54 N. Determine the mass of one chocolate

The weight of a cardboard box with 50 chocolates is 54 N. Determine the mass of one chocolate bar if the weight of the empty box is 400 g.

Initial data: n (number of chocolates in a box) = 50 pieces; P (weight of the cardboard box) = 54 N; m (empty box weight) = 400 g (0.4 kg).

Reference data: g (acceleration due to gravity) ≈ 10 m / s2.

1) Weight of the cardboard box with chocolates: M = P / g = 54/10 = 5.4 kg.

2) The mass of chocolates in the box: msh = M – m = 5.4 – 0.4 = 5 kg.

3) The mass of one chocolate bar: m1 = msh / n = 5/50 = 0.1 kg (100 g).

Answer: The mass of one chocolate bar is 100 grams.
