Answer: 6.6 moles of aluminium

Step-by-step explanation:

According to avogadro's law, 1 mole of every substance weighs equal to its molecular mass and contains avogadro's number
6.023* 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]* 3.30=6.6 moles of aluminium

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