The solution contains 60% (w/w) solute and its density is #2" g/cc"#

This means 100g solution which has volume #(100g)/(2g/"cc")= 50 c c# or 50mL will contain 60g solute.

So 1000mL 0r 1L solution contain #(60xx1000)/50g=1200g# solute
Molar mass of solute #80" g/mol"#

So molarity of the solution#="Strength in g/L"/"molar mass"#

#=(1200g/L)/(80g/"mol")=15M#
