How many atoms are in a sample of nitric acid?
To find the number of atoms in a sample of nitric acid, we use Avogadro's number: (0.0199914 mol) (6.022 x 10^23 formula units/mol) = 1.203882 x 10^22 formula units. Since nitric acid (HNO3) has 17 atoms per formula unit, the calculation continues as follows: (1.203882 x 10^22 formula units) (17 atoms / formula unit) = 2.0466 x 10^23 atoms.

How many moles are present in 1 gram of an atomic particle?
1 gram of an atomic particle is equal to the moles present in it. As we know that there are equal gram atoms present in one mole of atom, so we can say 1 gram of an atomic particle is equal to the moles present in it.
How many atoms are in the aluminum sulfate sample?
First, we need to determine the number of atoms in our sample of aluminum sulfate: ((0.0199914 mol) (6.022 x 10 23 formula units/mol)) = 1.203882 x 10 22 formula units. Then, we calculate the total number of atoms by multiplying the number of formula units by the number of atoms in each formula unit.
