Question

There are _________ pennies in 1.500 moles of pennies? (for scientific notation, use the ^ symbol similar to 2.02 x 10^5)

Answer 1

9.03 x 10²³ atoms in the pennies

Step-by-step explanation:

I suspect you want to find the number of atoms that makes up the given moles of the pennies:

Number of moles of pennies = 1.5 moles

Solution:

The mole can be defined as the amount of a substance that contains Avogadro's number of particles i.e 6.02 x 10²³atoms.

number of atoms = number of moles x 6.02 x 10²³ = 1.5 x 6.02 x 10²³

number of atoms = 9.03 x 10²³ atoms
