One mole of 12C has a mass of 12.00000 grams (exactly, by definition).
One mole of 13C has a mass of 13.00335 grams.
One mole of 14C has a mass of 14.00324 grams.
One mole of natural carbon - i.e. a sample with the ration of isotopes equal to that in nature - has a mass of 12.0107 grams.
The formula for carbon dioxide is CO2. The mass of carbon is 12 grams. The mass of oxygen is 16 grams, and there are two molecules of oxygen, so that's 32 grams. To calculate the mass of a mole, one would add those figures together. The mass of one mole of carbon dioxide is 44 grams.
mention whether it is carbon dioxide or cobalt molecule.
The mass of a mole of carbon dioxide is approximately 44 grams.
Fourty-four amu.

If the atomic mass of a carbon is 12 amu, 1 mole of pure carbon will have a mass of 12 g. (that's the way an a.m.u. is defined: 1 a.m.u. = 1/12th of the mass of C-12 isotope atom)
To find the molecular formula of carbon monoxide (CO), first find its empirical formula. The empirical formula is CO (1:1 ratio of atoms). Since the molecular mass of CO is 28.01 g/mol, and carbon's molar mass is 12.01 g/mol, the mass of oxygen in CO is 28.01 - 12.01 = 16 g/mol. Since the molecular mass of oxygen is 32.00 g/mol, CO's molecular formula is CO2.
The Mr of Carbon monoxide (CO) is 28, since Ar of Carbon is 12 and Ar of Oxygen is 16. Then proportion by mass will be simple ratio of 12 to 16 giving 3:4
1 mole of iron atoms has the greatest mass - 55,845 g.
Carbon monoxide is composed of one carbon atom and one oxygen atom.
In one mole of CO2, there is one mole of carbon (C). So if you have 1 mole of CO2, you have 1 mole of carbon.
If the atomic mass of a carbon is 12 amu, 1 mole of pure carbon will have a mass of 12 g. (that's the way an a.m.u. is defined: 1 a.m.u. = 1/12th of the mass of C-12 isotope atom)
The chemical equation for the decomposition of zinc carbonate is ZnCO3 → ZnO + CO2. From the equation, we see that 1 mole of zinc carbonate produces 1 mole of carbon dioxide. Zinc carbonate has a molar mass of 125.4 g/mol and carbon dioxide has a molar mass of 44.01 g/mol. By using stoichiometry, we can calculate that 125g of zinc carbonate produces 44.01g of carbon dioxide.

it can be said that 1 mole oflithium is equal in mass to its molar mass wwhich is 6.94 g/mol
We use the equation: Mass = Number of moles * Molecular or atomic mass Since the number of moles is 1 ("one mole of carbon-12 atoms") and the atomic mass of carbon-12 atoms is 12, hence the mass would be 12 grams. Note that the unit grams (g) is used here, as it is the SI unit for mass measurement. I hope this is useful! :)
1 mole of carbon weighs 12.01 gSo 3.2 mole will weigh 38.42 g
The Mr of Carbon monoxide (CO) is 28, since Ar of Carbon is 12 and Ar of Oxygen is 16. Then proportion by mass will be simple ratio of 12 to 16 giving 3:4
The proportion by number of atoms in carbon dioxide is 1:2. The atomic weight of carbon is 12.011 and the atomic weight of oxygen is 15.9994. Therefore, the proportion by mass of carbon to oxygen in carbon dioxide is 12.011/(2 X 15.9994) = 0.37536 or 37.536 %, to the justified number of significant digits.
1 mole of iron atoms has the greatest mass - 55,845 g.
Let us use the usual example, carbon, to show you the process.1 atom Carbon (1 mole carbon/6.022 X 1023)(12.01 grams/1 mole carbon)= 2 X 10 -23 grams in one atom carbon==========================(compare to mass of electron and proton )
1 x carbon and 1 x oxygen molecule carbon and monoxide monoxide is one oxygen molecule
