Step-by-step explanation:

To calculate the concentration of the glucose solution, you can use the formula:

Concentration (in g/mL) = Mass of solute (in g) / Volume of solution (in mL)

First, calculate the mass of the solvent in the solution:

Volume of solution = 475 mL

Density of solvent = 0.94 g/mL

Mass of solvent = Volume of solution × Density of solvent

Mass of solvent = 475 mL × 0.94 g/mL = 446.5 g

Now, calculate the mass of the solute (glucose), which is given as 13 g.

Now, use the formula to calculate the concentration:

Concentration (in g/mL) = Mass of solute (in g) / Volume of solution (in mL)

Concentration = 13 g / (475 mL + 446.5 g)

Concentration ≈ 13 g / 921.5 mL

Now, you can simplify this concentration:

Concentration ≈ 0.0141 g/mL

So, the concentration of the glucose solution is approximately 0.0141 g/mL.
