High Energy Materials Research Laboratory QC Chemist Interview Questions and Answers

To prepare a 1M, 1N solution, you need to calculate the amount of solute needed based on the molarity and normality of the solution.

• Calculate the molecular weight of the solute

• Determine the volume of solvent needed

• Measure out the calculated amount of solute and dissolve it in the solvent to make the final volume of the solution

• Verify the concentration using appropriate analytical techniques

Molarity is a measure of the concentration of a solute in a solution, expressed as the number of moles of solute per liter of solution.

• Molarity is calculated by dividing the number of moles of solute by the volume of the solution in liters.

• It is represented by the symbol 'M'.

• For example, a solution containing 0.5 moles of solute in 1 liter of solution has a molarity of 0.5 M.
