Explanation:
For SF6;
Since;
1.25 g of S corresponds to 4.44g of F
1 g of sulphur corresponds to 1 * 4.44/1.25 = 3.55
For SF4;
Since;
1.88 g of S corresponds to 4.44g of F
1 g of sulphur corresponds to 1 * 4.44/ 1.88 = 2.36
Hence;
Mass of oxygen per gram of sulphur in SF6/Mass of oxygen per gram of sulphur in SF4
=
3.55/2.36 = 1.5
Hence the law of multiple proportion is obeyed here.
Answer:
35.7 g
Kf - the cryoscopic constant of the solvent; b - the molality of the solution. So, the idea here is that you can only dissolve 35.7 g of sodium chloride, NaCl, in water at 0∘C.
Explanation:
The final answer is 2.25 atm

I took this quiz and the correct answer is not A.
4Na3PO4 The 4 at the beginning of the formula is important, it means you multiply everything after it by 4 so you would instead get the answer,
D. 12 Sodium, 4 phosphorus, 16 oxygen
