Strength is equal to*NormalityNormality x Molecular weightNormality x gram equivalent weightNormality x Equivalent weight

The statement you provided appears to be an equation relating strength to normality and various weights used in chemistry. Let's clarify and analyze this expression, breaking it down to understand the relationships involved.

1. Break Down the Problem

The relationship can be summarized using:

• $\text{Strength} = \text{Normality} \times \text{Weight}$ We need to identify what type of "weight" is being referenced—molecular weight, gram equivalent weight, or equivalent weight.

2. Relevant Concepts

• Normality (N): Number of equivalents of solute per liter of solution.
• Molecular Weight (MW): The weight of one mole of a substance.
• Gram Equivalent Weight (GEW): The mass of a substance that will react with or replace one mole of hydrogen ions in a reaction.
• Equivalent Weight (EW): The weight of an element or compound that reacts with or replaces a fixed quantity of another element or compound.

3. Analysis and Detail

• Strength is commonly expressed in terms of concentration, and normality directly relates to how reactive a solution is based on the concentration of equivalents of solute.
• The equation you provided can imply multiple forms based on the context and the type of measurements in use.
  • For solutions: $\text{Strength} = \text{Normality} \times \text{Gram Equivalent Weight}$
  • This is useful in titrations where you may want to relate the concentration of a solution to its reactivity.

4. Verify and Summarize

In summary, the expression relates strength of a solution to its normality and respective weights based on chemical equivalences. Each type of weight approximates how many reacting species are present, determining the solution's effectiveness.

Final Answer

The relationship can be succinctly expressed as:

$\text{Strength} = \text{Normality} \times \text{Gram Equivalent Weight}$

This encapsulates how strength in a chemical context is measured based on normality and equivalent weight, which are crucial for understanding solution concentrations and reactivities in volumetric analyses.
