Question

What is the mass percent of each element in dichloromethane, CH2Cl2?
% C
% H
% Cl
​

Answer 1

Answer:

Carbon= 14.11%, Hydrogen = 2.353%, and Chlorine= 83.53%

Explanation:

mass percentage of C= 12/85 × 100 = 14.117%

Mass percentage of H2 = 2/85 ×100 = 2.353%

Mass percentage of Cl2 = 71/85 ×100 = 83.53%

Answer 2

The mass percent of elements in Dichloromethane are $83.485\%\;of\;CL$$%$$,\;2.374\%\;of\;H,\;14.141\%\;of\;C.$

Explanation:

• Dichloromethane is a colourless liquid, sweet, penetrating, ether-like odor, and noncombustible untill exposed to high temperature may emit toxic fumes.
• The molecular mass of dichloromethane is $84.93$g/mol.
• It can be decomposed by contact with flame while this process emits fumes of phosgene and hydrogen chloride.
• The mass percent can be calculated by dividing the mass of an element in $1$ mole of the compound by the compound's molar mass which result is multiplied by $100$.
