Aluminum, silicon, and oxygen form minerals known as aluminosilicates. How many moles of aluminum are in: 1.) 4.20 moles of pyrophyllite, Al2Si4O10(OH)2 2. )1.60 moles of mica, KAl3Si3O10(OH)2 3.) 4.60 moles of albite, NaAlSi3O8
Aluminum, silicon, and oxygen form minerals known as aluminosilicates. How many moles of aluminum are in:
1.) 4.20 moles of pyrophyllite, Al2Si4O10(OH)2
2. )1.60 moles of mica, KAl3Si3O10(OH)2
3.) 4.60 moles of albite, NaAlSi3O8
Given : mole of pyrophyllite = 4.20 moles
Moles of mica = 1.60
Moles of albite = 4.60
To find : total moles of aluminium in thses minerals.
Solution : As we know that, mole is the ratio of mass of substance and molar mass of that substance.
In a mineral the total moles of any element is depends on the the mole of mineral and number of atoms of that element present in the mineral.
Total moles of Al = mole of mineral × no. Of Al atom in the mineral formula
