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.

Respuesta :

Answer:

b.15 % ( m / v )

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)%
