## Question:

What is the mass of 1.70 mol of carbon-12?
A)20.4g
B)12.0g
C)7.06g
D)0.140g

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 =

Mass = moles × molecular mass

The molecular mass of the Carbon-12 isotope has been 12g/mol.

The given moles of carbon12 have been 1.70 mol

Substituting the values:

Mass of Carbon-12 = 1.70 mol × 12 g/mol

Mass of carbon12 = 20.4 grams
