Given data:
Volume of glucose solution = 2.00 L
Density of glucose = 1.15 g/ml = 1.15 * 10^3 g/L
Density of a substance is the amount of that substance present in a unit volume. i.e.
Density = Mass/volume
Therefore, Mass of glucose = Density of glucose solution * Volume of the solution
= 1.15 * 10^3 g/L * 2.00 L = 2.30*10^3 g
Now,
10^3 g = 1 kg
therefore a mass of 2.30*10^3 g = 1 kg * 2.30*10^3 g/10^3 g = 2.30 kg
