A penny has a mass of 2.50g and the moon has a mass of 7.35 X 10^22Use this information to answer the questions below. Be sure your answers have the correct number of significant digits.
What is the mass of 1 mole of pennies?
How many moles of pennies have a mass equal to the mass of the moon? Write your answer as a decimal, and round to one place?
One mole of pennies has a mass of 1.5055 x 10²⁴g. Approximately 0.049 moles of pennies have a mass equal to the mass of the moon, which is 7.35 x 10²²g.To calculate the mass of 1 mole of pennies, we will use the given average mass of a single penny and the definition of a mole. A mole is Avogadro's number of items, which is approximately 6.022 \u00d7 10²³ items.The mass of one penny is 2.50g. Therefore, the mass of one mole of pennies (6.022 \u00d7 10²³ pennies) is calculated by multiplying the mass of one penny by Avogadro's number:Mass of 1 mole of pennies = 2.50g \u00d7 6.022 \u00d7 10²³ = 1.5055 \u00d7 10²⁴gTo find how many moles of pennies have a mass equal to the mass of the moon, we divide the moon's mass by the mass of one mole of pennies:Moles of pennies = Mass of the moon / Mass of 1 mole of penniesMoles of pennies = (7.35 \u00d7 10²²g) / (1.5055 \u00d7 10²⁴g/mole) \u2248 0.049 molesSo, approximately 0.049 moles of pennies have a mass equal to the mass of the moon, rounded to two significant figures....
