Answer:

Given:

Mass of glucose (m) = 281.1 g

Molar mass of glucose (MM) = 180.2 g/mol

Volume of solution (V) = 325 mL

First, let's convert the volume of the solution from milliliters (mL) to liters (L):

V = 325 mL = 325/1000 L = 0.325 L

Next, we can calculate the mass of glucose in the solution using its molar mass and the given mass:

moles of glucose (n) = m / MM

n = 281.1 g / 180.2 g/mol

Now, we need to calculate the mass percent by volume:

mass percent by volume = (mass of glucose / mass of solution) x 100

mass of solution = mass of glucose

mass percent by volume = (mass of glucose / mass of solution) x 100

= (n x MM / V) x 100

Substituting the values:

mass percent by volume = ((281.1 g / 180.2 g/mol) x 180.2 g/mol) / 0.325 L) x 100

Calculating this expression will give us the mass percent by volume of glucose in the solution.
