Question

3. Determine the percentage by volume in a solution that contains 350 mL of rubbing alcohol in a 500 mL of solution

Answer 1

Answer:

23.33

Explanation:

Given:  

350 mL (Mass of solute)

500mL(mass of solution)

Required:  

Percentage of Mass

                                 

Formula:

                                 Mass of solution

Percentage of Mass   ____________  ×100%

                                 Mass of solute

 

Solution:                                          

                                           350mL

Percentage of Mass   ____________ ×100 =  23.33

                                           500mL                                                                                             hope it helps

Answer 2

Given - Volume of rubbing alcohol : 350 ml

Volume of solution : 500 ml

Find - Percentage by volume

Solution - In the given solution, rubbing alcohol is the solute. The formula of percentage by volume is volume of solute/volume of solution*100

Now, keeping the values in formula to get percentage by volume.

Percentage by volume in solution = (350/500)*100

Percentage by volume in solution = 70%

Hence, the percentage by volume is 70%.
