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

Explanation:
The wide range of impurities cause the diverse amount of colors and many varieties. The green color in emerald is usually caused by traces of the element chromium, and the blue color of aquamarine usually by iron.
Usually when we talk about uneven heating of the Earth's surface we are discussing convection. The uneven heating results in some of the atmosphere to be warmer than other parts and changes in volume and pressure which result in updrafts and can cause thunderstorms and other violent weather.
