Question

3.30 moles of pyrophyllite, Al2Si4O10(OH)2How many moles of Al are in this compound?

Answer 1

Answer: 6.6 moles of aluminium

Explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number $6.023\times 10^{23}$ of particles.

1 molecule of $Al_2Si_4O_{10}(OH)_2$ contains = 2 atoms of aluminium

1 mole of $Al_2Si_4O_{10}(OH)_2$ contains = 2 moles of aluminium

Thus 3.30 moles of $Al_2Si_4O_{10}(OH)_2$ contain =$\frac{2}{1]\times 3.30=6.6$ moles of aluminium

Thus there are 6.6 moles of aluminium in the given compound.
