Question #066f0

Answer 1

`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"`
