Answer:
The answer is B. 11
Explanation:
I did the math and used what I know to find the answer. B is correct.
Answer:
0.088mole
Explanation:
Given parameters:
Mass of the compound = 5.125g
Unknown:
Number of moles = ?
Solution:
To solve this problem, we need first find the molar mass of the given compound.
Molar mass of NaCl = 23 + 35.5 = 58.5g/mol
So;
Number of moles = = = 0.088mole
Answer:
See Explanation
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.
