Question

To make a 0.500 M solution, one could take 0.500 moles of solute and add....

choose the correct answer below

enough solvent to make 1.00 kg of solution.

1.00 L of solvent.

enough solvent to make 1.00 L of solution.

1.00 kg of solvent.

Answer 1

molarity = number of moles of solute / volume of solution in L

0.500 M = 0.500 mole / volume of solution in L

volume of solution in L = 0.500 / 0.500 = 1.00 L

Therefore, to make a 0.500 M solution, one could take 0.500 mole of solute and add enough solvent to make 1.00 L of solution. option 3 is correct.

option 2) add 1L of solvent is not correct because the addition of 1L of solvent will make volume of greater than 1L and molarity less than 0.500 M. sol it is not correct.
