Nathaniel Sellers · Answer 1

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.
