Using the formula M1V1 = M2V2 , how many milliliters of a 2. 50 M hydrochloric acid solution is required to make 100. 0 mL of a
gladu [14]

Dilution of the solution can be calculated by the formula of the molarity and volume. The initial volume of 2.50 M solution was 30 mL.

<h3>What is the relationship between molar concentration and dilution?</h3>

Molar concentration or the dilution factor is in an inverse relationship and with an increase in the dilution, the molarity of the solution decreases.

Given,

Initial molarity = 2.50 M

initial volume = ?

Final molarity = 0.750 M

Final volume = 100.0 ml

Substituting values in the formula:

\begin{aligned}\rm V_{1} &= \rm \dfrac{M_{2}V_{2}}{M_{1}}\\\\&= \dfrac{0.750 \times 100}{2.50}\\\\&= 30 \;\rm mL\end{aligned}

Therefore, 30 mL was the initial volume of the solution before it was diluted.

The chemistry of living things and living systems created a new combined field in science known as
Anastasy [175]

Answer:

Biochemistry.

Explanation:

Biochemistry can be defined as the branch of science that deals with the study of the chemical processes, physio-chemical reactions and various substances that are found in living organisms such as animals, plants, and microorganisms.

Simply stated, biochemistry is a field in science that combines both the elements of biology and chemistry in order to study living organisms.

For example, all living organisms have the ability to engage in respiration in other to breathe in oxygen to stay alive. Thus, biochemistry helps us to understand respiration as a physio-chemical process that converts glucose into a form of energy (Adenosine Triphosphate-ATP) that is beneficial to all living organisms.

Hence, the chemistry of living things and living systems created a new combined field in science known as biochemistry.

Which salt is the most common found in ocean water?
Ivenika [448]

Answer:

Sodium chloride

Explanation:

There are several salts in seawater, but the most abundant is ordinary table salt or sodium chloride (NaCl). Sodium chloride, like other salts, dissolves in water into its ions, so this is really a question about which ions are present in the greatest concentration. Sodium chloride dissociates into Na+ and Cl- ions.
