Which of the following correctly describes how to convert a solution's concentration from millimolarity (mM) to molarity (M)?
A
Divide the millimolarity value by 1000.
B
Add 1000 to the millimolarity value.
C
Multiply the millimolarity value by 1000.
D
Subtract 1000 from the millimolarity value.
Verified step by step guidance1
Understand the units involved: millimolarity (mM) means millimoles per liter, and molarity (M) means moles per liter.
Recall the relationship between millimoles and moles: 1 mole = 1000 millimoles.
To convert from millimolarity to molarity, you need to convert millimoles to moles by dividing the millimolarity value by 1000.
Express the conversion mathematically as: \(M = \frac{mM}{1000}\), where \(M\) is molarity and \(mM\) is millimolarity.
Therefore, the correct method is to divide the millimolarity value by 1000 to get the molarity.
