Convert 6.35 grams of aluminum sulfate to moles

There are 0.0186 moles of formula units in 6.35 grams of aluminum sulfate .

Explanation:

What's the empirical formula of aluminum sulfate?

Sulfate is an anion with a charge of -2 per ion. When sulfate ions are bonded to metals, the compound is likely ionic.

Aluminum is a group III metal. Its ions tend to carry a charge of +3 per ion.

The empirical formula of an ionic compound shall balance the charge on ions with as few ions as possible.

The least common multiple of 2 and 3 is 6. That is:

Pairing three ions with two will balance the charge. Hence the empirical formula: .

What's the mass of one mole of aluminum sulfate? In other words, what's the formula mass of ?

Refer to a modern periodic table for relative atomic mass data:

There are

in one formula unit of .

Hence the formula mass of :
