Allicin (c6h10os2) contains 59.9 g of carbon, 21.7 g of hydrogen, 24.4 g of oxygen, and sulfur. what is the mass percent of sulfur in a 162 g sample of the compound?
a) 13.40%
b) 15.06%
c) 21.04%
d) 34.57%
e) 36.98%

Answer : The correct option is, (d) 34.57 %

Explanation: Given,

Mass of C = 59.9 g

Mass of H = 21.7 g

Mass of O and S = 24.4 g

Mass of sample = 162 g

First we have to calculate the mass of sulfur.

Total mass of allicin = Mass of C + Mass of H + Mass of O and S

Total mass of allicin = 59.9 + 21.7 + 24.4

Total mass of allicin = 106 g

Mass of sulfur = Mass of sample - Total mass of allicin

Mass of sulfur = 162 - 106

Mass of sulfur = 56 g

Now we have to calculate the mass percent of sulfur.

Formula used :

Now put all the given values in this formula, we get:

Therefore, the mass percent of sulfur is 34.57 %

answer:

the answer is 6 valence electrons.

explanation:

valence is the # of electrons on the outer most shell of an atom.

oxygen has 6.

although, the valency of oxygen is 2, because it only needs to make 2 covalent bonds, or gain 2 electrons, to achieve the stable octet configuration of a noble gas.

that's it!
