Please somebody this is due tonight and I have no idea... 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 (energy contained) in a standard bar, to fewer than 250. The planet Mars would have a mass how many times greater than the mole of Mars bars? Assume the mass of Mars is 6.39 x 10^23 kilograms.
