How many moles of pennies would have a mass equal to the mass of the moon?

The calculation to determine the number of moles of pennies that would have a mass equal to the moon's mass involves converting the mass of the moon to grams, then dividing it by the mass of one mole of pennies.

When calculating the number of moles of pennies that would have a mass equal to the mass of the moon, we first need to convert the mass of the moon from kilograms to grams. The mass of the moon is approximately 7.35 x 10^25 g.

One mole of a substance is defined by its molecular or atomic weight in grams. Given that a penny has a mass of 2.5 g, one mole of pennies would equal 2.5 g. To find how many moles of pennies would have a mass equal to the moon's mass, we need to divide the mass of the moon by the mass of one mole of pennies.

Therefore, the calculation would be as follows:

(7.35 x 10^25 g) / (2.5 g/mole) = 2.94 x 10^25 moles

Therefore, there would be approximately 2.94 x 10^25 moles of pennies having a mass equal to the moon's mass.
