How many grams are in 4.81 x 10^24 atoms of li?

We are given with a compound, Lithium (Li) having a 4.8x 10 ^24 atoms. We are tasked to solve for it's corresponding grams.Note that 1 mol=6.022x10^{23} atoms and Li has 6.94 g/mol, hence,g Li= 4.8x 10 ^24 atoms x 1 mol/6.022x10^{23} atoms x  6.94 g Li/1mol Li= 
55.32 g

 Therefore, the grams of Lithium is 55.32 g.

Yes you are correct use the scientific method
