The weight of a Mars bar has recently dropped from 58 grams to 51 grams. Mars says it's to encourage people to eat more healthily and keep the number of calories (the energy contained) in a standard bar, to fewer than 250. The planet Mars would have a mass how many times greater than a mole of Mars bars? Assume the mass of the Mars is 6.39 × 1023 kilograms.

Answer:
12.4×10²⁶
Explanation:
Mass of the mars bar(chocolate) = 51 gm = 0.051 kg
mass of the planet mars = 6.39×10²³ kg
Therefore,
Mass of mars(planet) is 6.39×10²³/0.051 = 6.31×10²⁶/51
Approximately 12.4× 10²⁶ times greater than mass of the chocolate mars bar.
