Find the percentage composition of a compound that contains 1.94 g of carbon, 0.48 g of hydrogen, and 2.58 g of sulfur.
Svetradugi [14.3K]

Answer : The percentage composition of carbon, hydrogen and sulfur in a compound is, 38.8 %, 9.6 % and 51.6 % respectively.

Explanation :

To calculate the percentage composition of element in sample, we use the equation:

\%\text{ composition of element}=\frac{\text{Mass of element}}{\text{Mass of sample}}\times 100

Given:

Mass of carbon = 1.94 g

Mass of hydrogen = 0.48 g

Mass of sulfur = 2.58 g

First we have to calculate the mass of sample.

Mass of sample = Mass of carbon + Mass of hydrogen + Mass of sulfur

Mass of sample = 1.94 + 0.48 + 2.58 = 5.0 g

Now we have to calculate the percentage composition of a compound.

\%\text{ composition of carbon}=\frac{1.94g}{5.0g}\times 100=38.8\%

\%\text{ composition of hydrogen}=\frac{0.48g}{5.0g}\times 100=9.6\%

\%\text{ composition of sulfur}=\frac{2.58g}{5.0g}\times 100=51.6\%

Hence, the percentage composition of carbon, hydrogen and sulfur in a compound is, 38.8 %, 9.6 % and 51.6 % respectively.

Arada [10]

Answer:

The correct option is: "Vitamin B12 (cobalamin) is not found in the vegan diet and is very low in the lacto-vegetarian diet"

Explanation:

Homocysteine is a VERY IMPORTANT type of amino acid, a chemical that the body uses to make proteins. Normally, vitamin B12, vitamin B6, and folic acid break down homocysteine and transform it into other substances that the body needs. There should be very little homocysteine left in the bloodstream. If you have high homocysteine levels in your blood, that could be a sign of a vitamin deficiency of the vitamins listed above, a heart condition, or a rare inherited disorder.
