write the formula for normality, formality and molality
Answers
Answer:
1.Normality Formula in chemistry is one of the important terms. Thus, we use it to measure the concentration of a solution.
2.The formality of a solution is defined as the number of formula mass of any solute dissolved
3.Molality is the number of moles of solute dissolved in one kilogram of solvent. Molarity
Explanation:
hope it helps
Answer:
normality is defined as the number of equivalent weight (or simply equivalents ,eq) of solute dissolved per liter of solution (equivalent /l = n )( equation 1) normality is used in place of molarity because often 1 mole of acid does not neutralize 1 mole of base.
formula of formality( nacl ) mass of sodium chloride=23+35.5=58.5
density=mass/volume mass=density x volume mass=0.975g/ml x 350 ml mass =341.25g mass =0.341kg .so , molality=moles of solute / mass of solvent (kg) molality=0.0117mol/0.341kg molality=0.034mol/ kg
