Question

What is the molar mass of `Ca_5(PO_4)_3(OH)`?

Answer 1

`502g//mol`

Explanation:

To find the molar mass, we add the molar mass of each atom each time it occurs in the compound.
The individual molar masses may be looked up on the periodic table.

`5Ca+3P+13O+1H => (5xx40)+(3xx31)+(13xx16)+(1xx1)`

`=200+93+208+1`

`=502`.

This means that 1 mole (`6.023xx10^23` particles) of the given compound will have a mass of `502` grams.
