Answer:
1.5 mol.
Explanation:
- It is known that every 1.0 mole of compound or element contains Avogadro's number (6.022 x 10²³) of molecules or atoms.
Using cross multiplication:
1.0 mole of H₂ contains → 6.022 x 10²³ molecules.
??? mole of H₂ contains → 9.03 x 10²³ molecules.
∴ The no. of moles of H₂ contains (9.03 x 10²³ molecules) = (1.0 mol)(9.03 x 10²³ atoms)/(6.022 x 10²³ atoms) = 1.5 mol.
