Question

How many atoms are there in 1.00 mole of KNO3?

a. 1 atom
b. 3.01 x 10^24 atoms
c. 6.022 x 10^23 atoms
d. 5 atoms

Answer 1

There are 6.02E+23 atoms/molecules in one mole of substance. There would only be 5 atoms/molecules in one formula unit of KNO3.

Answer 2

According to my calculations, C should be correct as 1.00 mole of any substance is 6.022 x 10^23 which is known as Avogadro's number.
