1%
Explanation:
The crust is the thinnest layer of the earth accounting for only 1% total volume of the planets.
Compositionally, the earth is divided into three layers which are the crust, mantle and the core.
- The crust is the outermost layer of the earth. It rich in silicate minerals. The rocks are classified into igneous, sedimentary and metamorphic rocks.
- The mantle takes up about 84% of the total volume of the earth. It is located in between the crust and the core. It is predominantly made up of ferro-magnesian silicate minerals.
- The cores accounts for slightly 15% of the volume of the earth. It is the center of our geoid shaped earth. It is rich in iron and nickel metals.

The sugar reacts with the gas, turning it to a semi-solid and sticky substance; clogging the gas lines along with many other things.
Electrical to chemical energy
Explanation:
If the batteries in a flashlight are rechargeable, the energy conversion that would take place to recharge the battery is from electrical to chemical energy.
- A battery is an electrochemical cell in which chemical reactions produces electrical currents.
- This is a typical energy conversion from chemical to electrical energy.
- When such batteries are to be recharged, the revere process is followed.
- Electrical energy are used to drive chemical reactions.
- This in turn makes the battery recharged and on its own, it can further chemical reactions to produce electrical energy.
- During charging, the potential of the battery increases.

For this problem, we use the equation derived from Beer's Law as written below:
A = ∈LC,
where
A is the absorbance
∈ is the molar absorptivity
L is the path length of the cuvette
C is the concentration of the sample solution placed in the cuvette
To determine C, we have to know the rest of the parameters. Generally, the equation for C would be:
C = A/∈L = A/∈(1 cm)
C = A/∈
If you know the absorbance and the molar absorptivity in mol/L·cm, you can determine the value of C.
