D. How many GRAMS of fluorine are present in 7.92×10²² molecules of sulfur hexafluoride?

E.How many GRAMS of carbon are present in 4.72 moles of carbon tetrachloride, CCl₄?

F.How many MOLES of chlorine are present in 3.90 grams of carbon tetrachloride?

Answer 1

A. 1.44 moles SCl2 x 1 mol S / mol SCl2 x 6.02x1023 atoms of S/mol S = atoms of S (do the math)

B. 1.09x10²³ molecules SCl₂ x 1 mol SCl₂ / 6.02x10²³ molecules x 2 mol Cl / mol SCl₂ = mol Cl (do the math)

C. 6.29 g SF₆ x 1 mol SF₆/146 g x 6 mol F/mol SF₆ x 6.02x10²³ F atom/mol F = atoms of F (do the math)

You should be able to do the others.
