Rank the following aqueous solutions in order of increasing<br> (c) freezing point;
saveliy_v [14]

0.01 m AgNO_{3} < 0.03 m CuSO_{4}< 0.04 m urea

As molal concentration rises, so does freezing point depression. It can be expressed mathematically as ΔTf = Kfm.

<h3>What is Colligative Properties ?</h3>
  • The concentration of solute particles in a solution, not the composition of the solute, determines a colligative properties .
  • Osmotic pressure, boiling point elevation, freezing point depression, and vapor pressure reduction are examples of ligand-like properties.
<h3>What is freezing point depression?</h3>
  • When less of another non-volatile material is added, the temperature at which a substance freezes decreases, a process known as Freezing-point depression.
  • Examples include combining two solids together, such as contaminants in a finely powdered medicine, salt in water, alcohol in water.
  • An significant factor in workplace safety is freezing points.
  • If a substance is kept below its freezing point, it may become more or less dangerous.
  • The freezing point additionally offers a crucial safety standard for evaluating the impacts of worker exposure to cold conditions.

Lithium has two stable isotopes with masses of 6.01512 amu and 7.01600 amu. The average molar mass of Li is 6.941 amu. What is t
Dvinal [7]

Answer :  The percent abundance of Li isotope-1 and Li isotope-2 is, 6.94 % and 93.1 % respectively.

Explanation :

Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.

Formula used to calculate average atomic mass follows:

\text{Average atomic mass }=\sum_{i=1}^n\text{(Atomic mass of an isotopes)}_i\times \text{(Fractional abundance})_i   .....(1)

Let the fractional abundance of Li isotope-1 be 'x' and the fractional abundance of Li isotope-2 will be '100-x'

For Li isotope-1 :

Mass of Li isotope-1 = 6.01512 amu

Fractional abundance of Li isotope-1 = x

For Li isotope-2 :

Mass of Li isotope-2 = 7.01600 amu

Fractional abundance of Li isotope-2 = 100-x

Average atomic mass of Li = 6.941 amu

Putting values in equation 1, we get:

6.941=[(6.01512\times x)+(7.01600\times (100-x))]

By solving the term 'x', we get:

x=694.048

Percent abundance of Li isotope-1 = \frac{694.048}{100}=6.94\%

Percent abundance of Li isotope-2 = 100 - x = 100-6.94 = 93.1 %
