First of all, carbon dioxide is a molecule and hence the question should be: What is the molecular mass of carbon dioxide? and the answer is 12 + (2 x 16) = 48
The molar mass of sodium acetate is 82,03. The molar mass of carbon dioxide is 44,01.
The molecular formula of carbon dioxide is CO2
It depends on the molecule. Carbon dioxide has a molecular mass of about 44 AMU, but most other molecules do not.
In terms of proportion of molecules that are carbon, 33% (formula: CO2 which means that there are 2 oxygens and 1 carbon). If you mean in terms of mass, then carbon is 27.27% of the molecule (Two oxygens at a molecular mass of 16 each, and one carbon at a molecular mass of 12) by mass.
The gram molecular mass of hexane is 86.18. Therefore, 25.0 g of hexane constitute 25.0/86.18 or 0.290 moles. Each mole of hexane contains six carbon atoms and therefore will produce six molecules of carbon dioxide by burning in an excess of oxygen. 6 X 0.290 = 1.74 moles of carbon dioxide. The gram molecular mass of carbon dioxide is 44.00. Therefore, the mass of carbon dioxide produced will be 1.74 X 44.00 or 76.6 grams of carbon dioxide, to the justified number of significant digits.
The density of a gas is directly propotional to its molecular mass. The main components of air are diatomic nitrogen and oxygen, which have molecular masses off approximately 28 AMU (atomic mass units) and 32 AMU respectively. Carbon dioxide has a molecular mass of approximately 44 AMU.
Carbon dioxide is a covalent molecule.
The density of a gas is proportional to its molecular mass. Nitrogen (N2) contains 2 nitrogen atoms each with a mass of about 14 AMU (atomic mass units) for a total molecular mass of about 44. Carbon dioxide (CO2) contains 2 atoms of oxygen, each with a mass of about 16 AMU and 1 carbon atom with a mass of about 12 AMU for a total mass of 44.
Carbon dioxide is a molecule.
Hydrogen has by far the smaller molecular mass (and atomic number) making it the smallest element
44 amu
