1 mole of carbon-14 atoms. (probably what your instructor is looking for)
More specifically,
One mole of the isobar (elements with the same number of nucleons) with 14 nucleons:
Be-14, B-14, C-14, N-14, O-14, F-14 are all suitable elements of which 1 mole of any of them (or a combination of all of them) will equal 14 grams.
Also, any 1 mole of a molecule with a molecular weight of 14 will weigh 14 grams.
An example:
Methane: CH4 IFF the carbon atom is a C-10 and the hydrogens are H-1.
Or half a mole of Silicon-28, and so on...
Mess with your professor a bit. It's good for them. haha!

What is the mass percent of nitrogen in ammonium carbonate (NH and Aacute) and iquestCO and Agrave?
The molar mass of ammonium carbonate is 96 g/mol (NH4)2CO3. The molar mass of nitrogen in the compound is 14 g/mol. Therefore, the mass percent of nitrogen in ammonium carbonate is (2*14 g/mol / 96 g/mol) * 100% = 29.2%.
What is the atomic mass of carbon-14?
12 g 14g/mole
If the formula for nitrogen dioxide is NO2 what is the molar mass of nitrogen dioxide to the nearest gram?
The approximate molar mass is about 46 g/mol (46.01 g/mol). You can estimate this by using the atomic mass numbers of nitrogen (8) and oxygen (16). N = 14.006 ~ 14 O = 15.994 ~ 16 14 + 2 (16) = 46
What is the mass of 14ml of mercury If the density of Mercury is 1.5g?
if you multiply:14 X 1.5 it should give you 21.
What is the molecular formula of compound CH2 with a molar mass of 42.0?
The molecular formula of compound CH2 with a molar mass of 42.0 g/mol is C2H4, which is ethylene. Each carbon has a molar mass of 12.0 g/mol, and each hydrogen has a molar mass of 1.0 g/mol, totaling 42.0 g/mol.
How many moles is 14 g of CO gas?
To determine the number of moles in 14 g of CO gas, you need to first calculate the molar mass of carbon monoxide (CO), which is 28.01 g/mol. Then, divide the given mass by the molar mass to find the number of moles. In this case, 14 g of CO gas is equal to 0.499 moles.
What is the mass of 14 ml of mercury?
Density of mercury is 13.534 g/cm3 around room temperature. An ml is 1 cm3, please work out the Mathematics yourselves.
What is the molecular formula of ch2 have a molar mass of 84g?
The molecular formula for a compound with a molar mass of 84 g/mol and a CH2 composition would be C4H8. This can be calculated by dividing the molar mass by the molar mass of a CH2 molecule (14 g/mol), which gives 6.
What is the molecular formula of the compound CH2 with molar mass 168?
The molar mass of CH2 is 14 g/mol (carbon: 12 g/mol, hydrogen: 1 g/mol). To get a molar mass of 168 g/mol, we need to multiply CH2 by 12. The molecular formula for the compound with a molar mass of 168 g/mol would be C12H24.
What is the mass percentage of N in NH3?
Nitrogen has an average atomic mass of about 14 while hydrogen has an average atomic mass of about 1, so the total molecular mass of NH3 is about 17. From this we find that the mass percentage of N in NH3 is about 14/17 = 82%. To get more precise numbers, look up the exact atomic masses from a periodic table.
What is the molecular formula of the compound CH2 with molar mass 42.0?
The unit CH2 has a gram atomic mass of 12.011 + 2(1.00794) or about 14. 42.0/14 = 3; therefore the molecular formula is C3H3.
What is the mass of 2 moles of carbon 14 dioxide?
2 * (14.0 + 2*16.0) = 92.0 g C(14)O2
