Molarity is defined as the number of moles of solute divided by the volume of the solvent
True or False
M = moles/volume of the solution.
Volume of the solution is not the same as volume of the solvent.
That is correct! Molarity is a unit of concentration in chemistry, defined as the number of moles of solute per liter of solution. It is represented by the symbol "M" and is often used to describe the concentration of a solute in a solution.
To calculate the molarity of a solution, you need to know the number of moles of solute and the volume of the solvent in liters. Here is the equation for molarity:
Molarity (M) = moles of solute (mol) / volume of solvent (L)
To determine the moles of solute, you can use the equation:
moles of solute = mass of solute (g) / molar mass of solute (g/mol)
First, you need to measure the mass of the solute using a balance. Then, find the molar mass of the solute by adding up the atomic masses of the elements in its chemical formula.
Next, measure the volume of the solvent using a graduated cylinder or a volumetric flask. Make sure to convert the volume to liters if it is given in a different unit.
Finally, plug the values into the molarity equation and calculate the answer. The resulting value will be in moles of solute per liter of solution, which is the molarity of the solution.
Remember to pay attention to the units and make sure they are consistent throughout the calculation.
