$\mathrm{de} n s t i y = 1.23 \text{ g/ml}$

#### Explanation:

$\mathrm{de} n s i t y = 1.23 \text{ g/ml} = \left(1.23 \times 1000\right) \frac{g}{L}$

So mass of solution =$\text{density "xx"volume} = 1.23 \times 1000 \times 0.002 = 2.46 g$

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 = $\frac{0.46}{0.002} = 230 \frac{g}{L}$

$\text{Molarity"="Strength in g/L"/ "Molar mass"=(230" g/L")/ "Molar mass}$
