How many carbon dioxide molecules are produced when 0.75 mol of propane is combusted?
If there are 0.75⋅mol of propane, coreactant O2 , and product CO2 are scaled down proportionally. That is, we require 0.75⋅mol×5⋅mol dioxygen gas, and 0.75⋅mol×3 carbon dioxide gas are evolved. And thus CO2 evolved, = 0.75⋅mol×3 = 2.25⋅mol CO2 gas.
What is the value of 1 mole of CO2?
44.01amu The molecular mass of carbon dioxide is 44.01amu. The molar mass of any compound is the mass in grams of one mole of that compound. One mole of carbon dioxide molecules has a mass of 44.01g, while one mole of sodium sulfide formula units has a mass of 78.04g.
What do you mean by 0.5 mole of CO2?
Carbon dioxide (CO2) has a molar mass of 44.01 g/mol . Here, there are 0.5 mol of the molecule. So, the mass of this sample is: m=44.01 gmol ⋅0.5mol. ≈22 g.

Mass of 1 mole (6.023 X 1023 molecules) of CO2 is about 44g.
How do you do stoichiometry?
Almost all stoichiometric problems can be solved in just four simple steps:
- Balance the equation.
- Convert units of a given substance to moles.
- Using the mole ratio, calculate the moles of substance yielded by the reaction.
- Convert moles of wanted substance to desired units.

What is conservation of mass How does it relate to this exercise?
What is conservation of mass and how does it relate to this exercise? Conservation of mass says the total mass of the reactants must equal the total mass of the products. As long as the carbon dioxide was not allowed to escape, the change in mass that occurred during the reaction should be zero.
How many molecules are there in 1.0 mole of CO2?
6.023 x 1023 molecules One mole of CO2 contains one mole of carbon and 2 moles of oxygen, i.e. 6.023 x 1023 atoms of C and 12.04 x 1023 atoms of oxygen. 6.023 x 1023 is Avogadro's number and represents the number of atoms or molecules present in one mole of a substance. So one mole of CO2 contains 6.023 x 1023 molecules of CO2.

What is SI unit of amount of substance state and explain the law of conservation of mass?
The law of conservation of mass states that mass in an isolated system is neither created nor destroyed by chemical reactions or physical transformations. According to the law of conservation of mass, the mass of the products in a chemical reaction must equal the mass of the reactants.
Why was it necessary to add the baking soda to the vinegar inside a plastic pouch?
Why was it necessary to add the baking soda to the vinegar inside a plastic pouch? Dropping the baking soda into the vinegar in a plastic pouch prevents the reaction from occurring immediately once the baking soda is added.
What is the number of particles in 1.5 moles of CO2?
1.5 mole of C = 6.022 x 102 x 1.5 = 9.033 x 1023 atoms of carbon.
