Hint: The gram formulation mass of a substance is identified as the mass of one mole. The meaning of molarity implies that you can find the molarity of an answer on the off chance that you know the absolute number of moles of the solute and the complete volume of the solution. In this way, to calculate the concentration of a solution (in molarity), you need to divide moles of solute by complete volume.
Complete step by step answer:
You multiply the concentration (in moles per liter) by the volume in litres.
The number of moles of a substance in \[1\] litre of solution is called its molarity. Molarity is likewise considered as molar concentration since it is the proportion of a concentration of a solution The official symbol for molarity is (concentration), yet the vast majority use the image "\[M\] ".
\[M\] \[ = \]\[\;\] $\dfrac{n}{{\text{V}}}$
where n is the quantity of moles and V is the volume in liters.
We can improve this condition to get the quantity of moles:
\[n\] \[ = \] \[M\] \[x\] \[V\]
Example:
How many moles of NaCl are contained in \[0.300{\text{ }}L\] of \[0.400\] mol/L NaCl solution?
Soln:
We are given the volume of solution in litre and asked for the number of moles substance.
\[\;n{\text{ }} = {\text{ }}0.300{\text{ }}L{\text{ }}soln{\text{ }} \times {\text{ }}\left( {0.400{\text{ }}mol{\text{ }}NaCl/1{\text{ }}L{\text{ }}soln} \right){\text{ }} = {\text{ }}0.120{\text{ }}mol{\text{ }}NaCl\]
Note:
Molarity is the quantity of moles of solute per liter of solution. A solute, which can be solid, fluid or gas, is a substance that is dissolved in a solvent. The solvent is another substance that is equipped for dissolving it inside its intermolecular spaces. Together, the dissolved solute and the solvent make a solution.
