500ml = 500cm3 = 0.5dm3 0.250M = 0.250mol/dm3 number of moles = molarity x volume number of moles = 0.250mol/dm3 x 0.5dm3 = 0.125mol 0.125mol of NaCl is needed to prepare the required solution.
300 cm3 equals 0.3 dm3
500mL is 0.0005m3
120 dm3 = 120 liters
7.5
400 cm3 to dm3
1 dm3 = 1000 cm3 :)
1 liter is 1 dm3
That is 500ml.
