<u>Answer:</u> The percent concentration ( % m/v) of dextrose in the solution is 2 %
<u>Explanation:</u>
We are given:
Mass of Yeast Extract = 5.0 grams
Mass of = 1.0 grams
Mass of = 0.5 grams
Mass of Dextrose = 20.0 grams
Mass of = 10. grams
Mass of Agar = 18.0 grams
Volume of solution = 1 L = 1000 mL (Conversion factor: 1 L = 1000 mL)
% (m/v) is defined as the concentration, which is mass of solute present in 100 mL of solution
To calculate the mass of solute, we apply unitary method:
In 1000 mL of solution, the mass of dextrose present is 20.0 grams
So, in 100 mL of solution, the mass of dextrose present will be =
Calculating the % (m/v) of dextrose, we get:
Hence, the percent concentration ( % m/v) of dextrose in the solution is 2 %
