Taking into account the definition od percentage composition, the percent composition of each compound in this sample is

Carbon: 73.46 %Hydrogen: 10.34 %Oxygen: 16.20 %

The Percentage Composition is a measure of the amount of mass that an element occupies in a compound and indicates the percentage by mass of each element that is part of a compound.

To calculate the percentage of composition, it is necessary to know the mass of the element in a known mass of the compound.

In this case, you know that a compound that contains 2.63 g of carbon, 0.370 g of hydrogen and 0.580 g of oxygen in a 3. 58 g sample of the compound.

Dividing the mass amount of each element present in the compound by the mass of the sample and multiplying it by 100 to obtain a percentage value, the percentage composition of each element is obtained:

Carbon: $\frac{2.63 g}{3.58 g}x100=$ 73.46 %Hydrogen: $\frac{0.37g}{3.58 g}x100=$ 10.34 %Oxygen: $\frac{0.58 g}{3.58 g}x100=$ 16.20 %

Finally, the percent composition of each compound in this sample is

Carbon: 73.46 %Hydrogen: 10.34 %Oxygen: 16.20 %

Answer from: aurorra

Carbon- 73.5%

Hydrogen - 10.3%

Oxygen - 16.2%

Explanation:

To find the percentage composition of each atom;

Carbon:

2.63/3.58 × 100 = 73.5%

Hydrogen:

0.370/3.58 × 100 = 10.3%

For oxygen:

0.580/3.58 × 100 = 16.2%

Answer from: Quest

You would be correct, boiling water does disinfect contamination. the property of disinfecting means to kill germs, bacteria and other pathogens or contamination that might cause an infection or cause a person to become sickly. a couple methods of disinfecting are using soap, other cleaning supplies or by simply "boiling" the contaminate. the reason why boiling water disinfects certain attributes is because some cells cannot survive the heat and pressure.
