An 18.5 g sample of tin (M = 118.7) combines with 10.0g of sulfur (M = 32.07) to form a compound. What is the empirical formula of this compound?

Molar mars in `g/(mol)`
Amount of Sn moles used `= 18.5/118.7 =0.156`
Amount of S moles used `= 10/32.07 =0.312`
`Sn: S =0.156 : 0.312 = 0.156/0.156 : 0.312/0.156 = 1:2`
So the empirical formula is `SnS_2`
