Question

What is the mass in grams of the following:

a) 3.011x10 to the 12th power atoms F

b)1.50x10 to the 23 power atoms Mg

Answer 1

1 mol F has a mass of 19.00 g and there are 6.02 x 10^23 atoms in that mass. Therefore, 19.00 x (3.011 x 10^12/6.02 x 10^23)= ??

The second one is done the same way. Look up the mass of Mg in the periodic table. I think it is 24.32 g/mol.
