For diluting a 10.0 M solution to a 1.00 M solution whether the instruction: “take 100.0 mL of the 10.0 M solution and add 900.0 mL water” is correct or not is to be explained. Concept introduction: Molarity ( M ) is one of the concentration terms that determine the number of moles of solute present in per liter of solution. Unit of molarity is mol/L . The expression to calculate the molarity of a solution when moles of solute and volume of solution are given is as follows: Molarity of solution ( M ) = moles of solute ( mol ) volume of solution ( L ) Dilution is the process of converting a concentrated solution into a dilute solution by adding more solvent. In the resultant solution, the amount of solute remain fixed but the volume of the solution increases resulting in a less concentrated solution.

Concept introduction:
Molarity (M) is one of the concentration terms that determine the number of moles of solute present in per liter of solution. Unit of molarity is mol/L.
The expression to calculate the molarity of a solution when moles of solute and volume of solution are given is as follows:
Molarity of solution(M)=moles of solute(mol)volume of solution(L)
Dilution is the process of converting a concentrated solution into a dilute solution by adding more solvent. In the resultant solution, the amount of solute remain fixed but the volume of the solution increases resulting in a less concentrated solution.
When 15.00 mL of 3.00 M NaOH was mixed in a calorimeter with 12.80 mL of 3.00 M HCl, both initially at room temperature (22.00 C), the temperature increased to 29.30 C. The resultant salt solution had a mass of 27.80 g and a specific heat capacity of 3.74 J/Kg. What is heat capacity of the calorimeter (in J/C)? Note: The molar enthalpy of neutralization per mole of HCl is -55.84 kJ/mol.
