ANSWER: 4
SF6 = 146 g/mole; 6F = 114 g
6F/SF6 = 114/146 X 100 = 78.08%
From the formula SF6, you can determine the total mass of each element in the compound by using molar mass.
1mol S x (32.06 g S/1mol S)= 32.06 g S
6 mol F x (19.00 g F/ 1 mol F) = 114.00 g F
Next add 32.06 g S + 114.00 g F = 146.06 g SF6
To find the mass percentage of F, take the grams of F and divide by the grams of SF6 and then multiple by 100.
(114.00 g F/146.06 g SF6) x 100 = 78.05 %
The closest answer is 4. 78.0%
