An aqueous solution contains 47% of A on volume basis. If the density of A is 1250 kg/m3, express the composition of A in weight %

Sure, here are the steps to solve this problem:

Step 1: Understand the problem The problem states that an aqueous solution contains 47% of A on a volume basis. This means that for every 100 units of the solution, 47 units are A. The density of A is given as 1250 kg/m3.

Step 2: Convert the volume percentage to mass We know that density = mass/volume. Therefore, mass = density * volume. So, the mass of A in 100 units of the solution = 1250 kg/m3 * 47 m3 = 58750 kg.

Step 3: Calculate the weight percentage The weight percentage is calculated as (mass of A / total mass) * 100. However, we don't know the total mass of the solution. We only know the mass of A.

Unfortunately, without additional information (like the density of the solution or the density and volume percentage of the other components of the solution), we can't calculate the weight percentage of A in the solution.
