(A) 46 u
(B) 44 u
(C) 40 u
(D) 45 u.
The relative molecular mass of CO2 is 44 u. Carbon has an atomic mass of 12.0107u and an atomic number of 6. Oxygen has an atomic mass of 15.999 u and an atomic number of 8. So, CO2 comprises two molecules of oxygen and one carbon molecule. taking the total mass of the atoms. Then, 1 x 12 + 2 x 16 = 44

Environmental issues by CO2
- Around the world, CO2 emissions poison our pristine air and create an impenetrable coating. In a sense, this sheet retains the heat inside the earth, contributing to global warming. This process is also known as the greenhouse effect.
- Burning fossil fuels releases pollutants into the atmosphere, reduces the amount of forest cover, and causes a rapid increase in industrial, agricultural, and horticultural activity, which alters the equilibrium of the climate system.
- A balance between solar energy going into the Earth and energy being reflected back into space determines the temperature of the planet. Carbon dioxide absorbs the heat that would otherwise be lost to space. If some of this energy is returned to Earth, it will heat up the atmosphere even more.
- The amount of greenhouse gases increases as carbon dioxide levels rise, trapping more heat. Due to the ice caps melting and the rising ocean levels brought on by this stored heat, flooding results.
As a result, CO2 has a 44u relative molecular mass.
The mass of a certain molecule is its molecular mass. Daltons are used to measure it (Da or u).
Summary:
Calculate the relative molecular mass of CO2. (A) 46 u (B) 44 u (C) 40 u (D) 45 u
The relative molecular mass of CO2 is 44u.
