Calculate the volume (in cm3) required to make a solution of concentration 0,6 mol.dm-3 if 0,2 moles of solute is present.

Answer 1

To calculate the volume of the solution, we can use the formula:

Volume (dm3) = amount of solute (mol) / concentration (mol.dm-3)

Given that 0,2 moles of solute is present and the concentration is 0,6 mol.dm-3:

Volume (dm3) = 0,2 mol / 0,6 mol.dm-3
Volume (dm3) = 0,333 dm3

Now, to convert the volume to cm3, we multiply by 1000:

Volume (cm3) = 0,333 dm3 * 1000
Volume (cm3) = 333,33 cm3

Therefore, the volume of the solution required to make a solution of concentration 0,6 mol.dm-3 with 0,2 moles of solute present is 333,33 cm3.
