Answer 1

Answer:

Explanation:

50 gm bismuth in 100 gm sol.

25 gm lead in 100 gm sol .

12.5 gm tin in 100 gm sol .

12.5 gm cadmium in 100 gm sol.

then now we will find their moles

bismuth= 50gm / 209= 0.2 mol

lead= 25gm / 207= 0.1mol

tin =12.5 / 119 = 0.1mol

cadmium = 12.5 / 112= 0.1 mol

Add all the mole and put in the equation

= tin mole / total mole

= 0.1 mol / 0.5 mol
