According to the molar concentration, if you have 550 ml of 7 M solution HCI and you want to make 3 L of diluted solution,the new concentration will be 1.28 M.
What is molar concentration?Molar concentration is defined as a measure by which concentration of chemical substances present in a solution are determined. It is defined in particular reference to solute concentration in a solution . Most commonly used unit for molar concentration is moles/liter.
The molar concentration depends on change in volume of the solution which is mainly due to thermal expansion. Molar concentration is calculated by the formula, molar concentration=mass/ molar mass ×1/volume of solution in liters.In case of two solutions it is calculated as, M₁V₁=M₂V₂ on substitution gives M₂=7×550/3000=1.28 M.
