Answer: Moles of solute particles are present in 272 mL solution of 0.242 M are 0.0658.
Explanation:
Molarity is defined as the number of moles of solute dissolved per Liter of the solution.
To calculate the number of moles for given molarity, we use the equation:
.....(1)
Molarity of solution = 0.242 M
Volume of solution = 272 mL
Putting values in equation 1, we get:
Thus moles of solute particles are present in 272 mL solution of 0.242 M are 0.0658.
