Sodium hydroxide solution 30% CAS 1310-73- 2 Suprapur® - Find MSDS or SDS, a COA, data sheets and more information.
CAS number:
Aluminum Al2713 has an atomic molar mass of 27 grams per mole.
Al has 13 protons (hence number 13) and it most common isotope 14 neutrons for a total mass of 27 amu. ( The 13 electrons add no measurable mass to the atom)
Take the grams and divide by the molar mass
= 2 moles
