Convert 25cm3 to dm3
=25/1000=0.025dm3
Change 585g to g/dm3
=585/0.025
=23400g/dm3
Molar mass of nacl=23+35.5=58.5
Conc in mol/dm3=conc in g/dm3/molar mass
Conc in mol/dm3=23400/58.5
=400mol/dm3 or 400M

Molarity=mass/molar mass * 1000/volume

molar mass of nacl=23+35.5=58.5

=5.85/58.5 * 1000/25
=5850/1462.5
=4mol dm-3
