Approximately 8.82*10^-3mol or 1.72g of platinum.

Explanation:

This is a very vague question, but I will assume you're looking for how much they weigh.

(5.31*10^21 mol.) * (mol)/(6.023*10^23mol.) approx 8.82*10^-3 mol

Note that mol. is referring to molecules and mol (without the period) is referring to moles.

8.82*10^-3 mol * (195.1g)/(mol) = 1.72g
