How many moles of atoms are in 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.

What is the number of moles of O atoms?

Calculate the number of oxygen atoms in 1 mole of O2. Solution — 1 molecule of O2 = 2 oxygen atoms So, 1 mole of O2 = 2 mole oxygen atoms = 2 × 6.022 × 1023 = 12.044 ×1023 oxygen atoms.
