The mass of 1.70 mol Carbon-12 has been 20.4 grams. Thus, option A is correct.
The mass can be given from moles, as moles have been the mass of the compound with respect to the molecular mass.
Moles have been given as:
Moles = [tex]\rm \dfrac{Mass}{Molecular\;mass}[/tex]
Mass = moles × molecular mass
The molecular mass of the Carbon-12 isotope has been 12g/mol.
The given moles of carbon-12 have been 1.70 mol
Substituting the values:
Mass of Carbon-12 = 1.70 mol × 12 g/mol
Mass of carbon-12 = 20.4 grams
The mass of 1.70 mol Carbon-12 has been 20.4 grams. Thus, option A is correct.
