How to convert millimolar to molar
The correct Answer and Explanation is :
To convert millimolar (mM) to molar (M), you simply divide the concentration in millimolar by 1,000 because “milli-” represents one-thousandth (1/1,000). Here’s the basic conversion formula:
[
M (Molar) = \frac{mM (Millimolar)}{1,000}
]
Example:
If you have a solution with a concentration of 150 millimolar (mM) and want to convert it to molar (M), you would perform the following calculation:
[
150 \, \text{mM} \div 1,000 = 0.150 \, \text{M}
]
So, 150 mM equals 0.150 M.
Detailed Explanation:
In chemistry, molarity (M) is a unit of concentration that indicates how many moles of a substance are present in one liter of solution. A mole is a fundamental unit in chemistry representing (6.022 \times 10^{23}) particles (atoms, molecules, etc.). For example, 1 M solution means there is 1 mole of solute in 1 liter of solution.
Millimolar (mM), on the other hand, is a subunit of molarity, where 1 millimole is equal to (1 \times 10^{-3}) (or 0.001) moles. Therefore, millimolar concentrations are used when the concentration of a solute in a solution is much smaller than a mole per liter. Since 1 millimolar is (1/1,000) of a molar, converting from mM to M requires dividing by 1,000.
Why the Conversion Matters:
Scientists and medical professionals often use molarity to measure the concentration of solutions in laboratory work or clinical settings. Being able to convert between millimolar and molar is essential for accurately preparing solutions, interpreting data, and communicating scientific results.
