Answer:

#denstiy = 1.23 " g/ml"#

Explanation:

#density = 1.23 " g/ml"=(1.23xx1000)g/L#

So mass of solution =#"density "xx"volume"=1.23xx1000xx0.002=2.46g#

If the solvent is water and solution is ideal then volume of water will be 0.002L=2ml and its mass will be 2g. ( Taking density of water 1g/ml)

So the mass of solute =(2.46-2)=0.46g

So strength in g/L = #0.46/0.002=230g/L#

#"Molarity"="Strength in g/L"/ "Molar mass"=(230" g/L")/ "Molar mass"#
