Question

What is the concentration, in percent by volume, of 15.3 mL of solute in 2.65 L of solution?

Answer 1

Given: 15ml of solute

          2.65L of solution

To find: concentration in percent by volume

Solution: concentration in percent of solute in a solution is defined as the amount of solute in a given amount of solution.

concentration in volume is the ratio of the volume of a solute to the volume of solution.

            Concentration = 15/2650

                                     = 0.0056

In percentage = 0.0056×100

                        = 0.56%

So the concentration, in percent by volume will be 0.56%

Answer 2

Concentration, in percent by volume, of 15.3 mL of solute in 2.65 L of solution is about 0.577 %

Given:

• 15.3 mL of solute
• 2.65 L of solution

To Find:

• Concentration, in percent by volume

Solution:

• Concentration (v/v) % = (Solute Volume/Solution Volume) x 100
• 1 Lite = 1000 ml

Step 1:

Convert 2.65 L Solution into mL

2.65 L = 2.65 x 1000 = 2650 mL

Step 2:

Calculate Concentration, in percent by volume by substituting values in formula

= (15.3/2650) x 100  %

= 153/265    %

≈  0.577 %

Concentration, in percent by volume, of 15.3 mL of solute in 2.65 L of solution is about 0.577 %
