Question

Wilma dissolves 10,00 grams of glucose with water and the final volume of solute and solvent is 66.67 mL. What is the concentration of glucose in her solution? a. 10% (m/v) O b.15.% (mv) O c.25 % (m/v) d. 30.% (m/v) e. None of the above.

Answer 1

b.15 % ( m / v )

Step-by-step explanation:

The percent concentration ( m / v ) =

mass of the solute / volume of the solution * 100

From the question , the mass of glucose = 10.00 g

The total volume of the solution = 66.67 mL

using the above formula ,and putting the respective values , the percent concentration ( m / v ) is calculated as -

The percent concentration ( m / v ) = 10.00 g / 66.67 mL * 100 = 15 (m/v)%
