Answer:
<h3>The answer is 0.73 g/mL</h3>
Explanation:
The density of a substance can be found by using the formula
From the question
mass = 620 g
volume = 850 mL
We have
We have the final answer as
<h3>0.73 g/mL</h3>
Hope this helps you
Answer:
1.239 * 10^8 Kg
Explanation:
Since all the electricity consumed comes from natural gas;
amount of electricity consumed = 700 * 300,000 = 2.1 * 10^8 kWh
So, amount of CO2 consumed is given by;
amount of electricity consumed * amount of CO2 per kWh
Hence,
Amount of CO2 = 2.1 * 10^8 kWh * 0.59 = 1.239 * 10^8 Kg
Condensation, because it is a phase change from gas to liquid
Answer:
Explanation:
Density is a characteristic property of a substance. The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume). The mass of atoms, their size, and how they are arranged determine the density of a substance.
The mass of gas in the tank has been 222 g. Thus, option B is correct.
The volume occupied by 1 mole of gas at standard temperature and pressure has been 22.4 L.
<h3>Computation for the Mass of gas</h3>
The volume of gas in the tank has been given as 170 L.
The moles of gas in the tank has been:
The moles of gas in the tank has been 7.58 mol.
The molar mass of the gas has been 32.0 g/mol.
The mass of gas has been calculated as:
Thus, the mass of gas in the tank has been 222 g. Thus, option B is correct.
