The rays of the sun will go directly to the trees, then
trees take up light that absorbs light energy which converting light to
chemical potential energy kept in chemical bonds. And when the trees cut into
woods and burnt it, it will convert to thermal energy.
The volume of cylinder is 100 mL, inner diameter is 3.2 cm thus, radius will be:
Volume of layer formed=
...... (1)
Volume of layer is also equal to sum of volume of gasoline and water.
Density of gasoline is 
and mass is 34 g thus, volume of gasoline will be:
Now, density of water is 
and mass is 34 g thus, volume of water will be:
Adding both the volumes, volume of layer will be:
Putting the values in equation (1) to solve for height of the layer,
Thus, height of layer is 10.25 cm
The molar mass of the gas that has a mass of 3.82 g and occupies a volume of 0.854 L is 106.66g/mol.
<h3>How to calculate molar mass?</h3>
The molar mass of a substance can be calculated by dividing the mass of the substance by its number of moles.
However, the number of moles of the gas in this question needs to be calculated first using the ideal gas law equation:
PV = nRT
Where;
- P = pressure
- V = volume
- n = number of moles
- T = temperature
- R = gas law constant
1.04 × 0.854 = n × 0.0821 × 302
0.888 = 24.79n
n = 0.888/24.79
n = 0.036mol
Molar mass of gas = 3.82g/0.036mol
Molar mass = 106.66g/mol
Therefore, the molar mass of the gas that has a mass of 3.82 g and occupies a volume of 0.854 L is 106.66g/mol.
