Chemistry question: What is the mass, in grams, of a sample of 6.12 * 1024 atoms of manganese (Mn) ?

6.12x10^24 atoms x 1 mol/6.02x10^23 atoms = 10.166 rounded to 10.2

10.2 mol x 54.9380g/1 mol = 558.505 = 559g

I was just wondering if I rounded to high to get the right amount of sig figs? Is my answer correct or should I change it?
