$Normality$ (नॉर्मलता) और $Molarity$ (मोलरता) के बीच कौन सा संबंध सही है?

• A
  $Normality \times \text{Molecular weight} = Molarity \times \text{Equivalent weight}$
• B
  $Normality \times \text{Equivalent weight} = Molarity \times \text{Molecular weight}$
• C
  $Molality \times \text{Molecular weight} = Normality \times \text{Molecular weight}$
• D
  $Molality \times \text{Equivalent weight} = Normality \times \text{Equivalent weight}$
