Find the percent composition of 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.

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

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:

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

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%

cytokinesis is the splitting of a cell membrane to form 2 identical daughter cells. it's similar to mitosis as both cells have identical copies of dna and cytokinesis is a step in the mitotic cycle.
