## How many atoms are there in 1 mole of HNO3?

Note the amounts of atoms of all the component in HNO3, which are 1 atom of Hydrogen, 1 atom of Nitrogen and 3 atoms of Oxygen. Multiply each of the atomic weights by the amount of atoms of each element contained in the compound. Add up the results to obtain the molar mass: 1 + 14 + (16 x 3) = 63 gr/mole.

## How many atoms of each kind are present in 1 molecule of HNO3?
