Answer :
According to molar concentration, the molarity of sucrose in the final solution is 0.0584 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 terms of moles, it's formula is given as molar concentration= number of moles /volume of solution in liters.
Initially the molarity of sucrose is determined as, number of moles /volume of solution in liters which is 0.146/0.2=0.0292 moles and then molarity after dilution is determined as, M₁V₁=M₂V₂, on substitution M₂=0.0292×10/50=0.0584 M.
Thus, the molarity of sucrose in this final solution is 0.0584 M.
