Question

The density of 3M nail solution is 1.259 ml.calculate molality of solution

Answer 1

Correct question:

Given:

• The density of 3M nail solution is 1.25 g/ml.

Find:

• Calculate molality of solution.

Calculations:

$\longrightarrow\sf{1.25 \times 1000}$

$\longrightarrow\sf{1250 \: gms}$

$\longrightarrow\sf{1250 - 3 \times 58.8}$

$\longrightarrow\sf{1074.68 \: g}$

.·. 1074.68 g is the volume.

Using formula:

★ ${\sf{\underline{\boxed{\orange{\sf{Density = \dfrac{Mass}{Volume} }}}}}}$

Required answer:

$\longrightarrow\sf{Density = \dfrac{3}{1074.80}}$

$\longrightarrow{\sf{\underline{\boxed{\red{\sf{2.7915 \: M }}}}}}$

.·. Morality is 2.7915.
