If 450 grams of dextrose are dissolved in 650ml Of water with a resultant volume of 1 liter what is the percent concentration (w/v) of dextrose

Mass volume percentage (% m/V) is a measure of concentration that indicates the number of grams of solute per 100 volume units of the solution. In other words, the volume percent of a component in the solution is defined as the ratio of the mass of the component to the volume of the solution, expressed as a percentage.

The mass volume percentage of a solution is determined by the following expression:

[tex]Mass volume percentage=\frac{mass of solute}{volume of solution}x100[/tex]

Percent concentration in this case

In this case, you know:

mass of solute= 450 grams
volume of solution= 1 L= 1000 mL

Replacing in the definition of mass volume percentage:

[tex]Mass volume percentage=\frac{450 grams}{1000 mL}x100[/tex]

Solving:

mass volume percentage= 45%

Finally, the percent concentration of dextrose is 45%.
