What is the percent composition of a 16.75 g sample of a compound containing 14.02 g oxygen and 2.73 g hydrogen? Select the correct answer below: 83.7% oxygen, 16.3% hydrogen O 17% oxygen, 13% hydrogen O 68.2% oxygen, 31.8% hydrogen 89.5% oxygen, 10.5% hydrogen ​

83.7% oxygen, 16.3% hydrogen

Explanation:

Mass of compound = 16.75 g

Mass of Oxygen = 14.02 g

Mass of Hydrogen =  2.73 g

Percentage composition = Mass of element /  Mass of compound    100%

Percentage composition of Oxygen = 14.02 g / 16.75 g    * 100%

Percentage composition of Oxygen = 0.837 * 100 = 83.7%

Percentage composition of Hydrogen = 2.73 g / 16.75 g    * 100%

Percentage composition of Hydrogen = 0.163 * 100 = 16.3%

The correct option is;

83.7% oxygen, 16.3% hydrogen

83.7% oxygen, 16.3% hydrogen

Explanation:

To determine the percent composition we can divide, our mass by total mass and afterwards, multiply by 100.

(Mass of O / Total mass) . 100 = % O

(Mass of H / Total mass) . 100 = % H

Remember that:

% O + % H = 100

Mass of O / Total mass + Mass of H / Total mass = 1

(14.02 g / 16.75g) . 100 = 83.7 %

(2.73 g /16.75g) . 100 = 16.3 %

practical process described pest part of scientific investigation.

because practical knowledge is powerful then therotical knowledge.

in the analysis of systems that involve fluid flow, we frequently encounter the combination of properties u and pv.
