What volume, in Liters, of a 2.00 M KCl solution contains 2.5kg of KCl? Molar mass of KCl= 74.55g/mole
Julli [10]
C_{m}=\frac{n}{V_{r}}\\\\
n=\frac{m_{s}}{M}\\\\
C_{m}=\frac{m_{s}}{MV_{r}} \ \ \ |*MV_{r}\\\\
C_{m}MV_{r}=m_{s} \ \ \ |:C_{m}M\\\\
V_{r}=\frac{m_{s}}{C_{m}M}\\\\\\
m=2.5kg=2500g\\
M=74.55\frac{g}{mol}\\
C_{m}=2\frac{mol}{L}\\\\
V_{r}=\frac{2500g}{2\frac{mol}{L}*74.55\frac{g}{mol}}\approx16.77L

What two categories of chemicals are based on carbon content?
zaharov [31]

Answer: Option (D) is the correct answer.

Explanation:

Inorganic compounds are the compounds which lack carbon atoms.

For example, water (H_{2}O) is an inorganic compound.

Whereas organic compounds are the compounds which have carbon atom(s). For example, methane (CH_{4}) is an organic compound.

On the other hand, molecules, compounds, living, non-living, ionic, and covalent categories of chemicals can either have carbon content or not have carbon content.

Thus, we can conclude that inorganic and organic categories of chemicals are based on carbon content.
