Radhika has four beakers, and each beaker contains 100 ml of acidic solution. The amount of acid in each beaker is given below.

Beaker 1 - 50 ml of acid
Beaker 2 - 25 ml of acid
Beaker 3 - 80 ml of acid
Beaker 4 - 75 ml of acid

Arrange these solutions in the order of their concentration, starting from the most diluted.

To determine the concentration of each solution in the beakers, we need to calculate the concentration in terms of acid per 100 ml of solution. Concentration is typically measured by the formula:
[ \text{Concentration} = \frac{\text{Amount of Acid (ml)}}{\text{Total Solution (ml)}} \times 100 %
Since each beaker contains 100 ml of solution, the concentration calculation for each beaker is straightforward. Let's calculate them one by one:

Beaker 1:

Acid: 50 ml
Concentration: 100 50 ​ × 100% = 50%


Beaker 2:

Acid: 25 ml
Concentration: 100 25 ​ × 100% = 25%


Beaker 3:

Acid: 80 ml
Concentration: 100 80 ​ × 100% = 80%


Beaker 4:

Acid: 75 ml
Concentration: 100 75 ​ × 100% = 75%



Now, to arrange these solutions in order of their concentration from the most diluted (least concentrated) to the most concentrated:

Beaker 2: 25% (most diluted)

Beaker 1: 50%

Beaker 4: 75%

Beaker 3: 80% (most concentrated)


So, the order from most diluted to most concentrated is: Beaker 2, Beaker 1, Beaker 4, Beaker 3.
