first you need a balanced equation, so:
24F2+S8 --> 8SF6
then find the no. of moles of s8 (which is 19g divided by molar mass of s8)
then use the reaction ratio of 24:1 to multiply your answer to get number of moles of fluorine
then convert from moles to mass using m=n*M
24F2+S8 --> 8SF6
then find the no. of moles of s8 (which is 19g divided by molar mass of s8)
then use the reaction ratio of 24:1 to multiply your answer to get number of moles of fluorine
then convert from moles to mass using m=n*M

19.0/256.56 multiply by 24 mol F2 multiply by 38g F2 after calculation will give you the mass in grams of F2.
