strength in milligrams is 0.3mg
What is Strength?
Mass of the solute in grams/Volume of the solution in litres equals the strength of the solution. The overall formula must be multiplied by 1000 if the volume is measured in millilitres (mL). The concentration of the solution, measured in grammes per litre, can be used to determine the solution's strength.
Molarity - The moles of solute per litre of solution is measured as molarity. For instance, when table salt is dissolved in water, water serves as both the solution and the solute. Sodium chloride weights 58.44 grammes per mole. One molar solution, or 1M, is created by dissolving 58.44 grammes of sodium chloride in one litre of water.
Relation between Molarity and Strength?
The volume of solute in one litre of a solution determines its strength. As a result, a solution's strength is calculated by multiplying its molecular mass by its molarity.
