Molarity is a unit of concentration. The concentration of a substance is the amount of substance present in a unit volume. According to convertunits.com, one mole per cubic meter is 1000 micromolar or 1 millimolar.
According to Dr. Kristy Bailey from Oklahoma City Community College, molarity is the concentration of a solution expressed as the number of moles of the solute per liter of solution. One molar is equivalent to one mole per liter. Therefore, a 10 micromolar solution contains 10 micromoles of solute per liter of solution or 0.00001 moles of solute per liter of solution. The number of moles can be calculated by dividing the mass of the solute by the molecular weight of the solute.
The prefix milli- represents a factor of 0.001 or 1E-3.This means that a 10 micromolar solution contains 0.001 x 10 = 0.01 millimoles of solute per liter of solution. This can also be expressed as 10 millimoles per milliliter, 0.01 moles per milliliter or 10000 micromoles per milliliter.Learn more about Chemistry
