0.468n

Explanation:

"number of moles"="mass"/"molar mass"

the mass in this case: 100g

molar mass: (looking at the periodic table because molar mass means the total mass of the atomic mass of all your elements)
=63.55+32.07+16x4+3(1.008x2+16)
=213.668

Therefore, "number of moles"=100/213.668=0.468n
