The correct answer for How many moles of atoms are in 7.00 g of 13c? express your answer numerically in moles?
number of moles = mass / molar mass
number of moles = 7 / 13
To know the number of atoms in 7/13 moles, we simply multiply the number of moles by Avogadro’s number as follows:
number of atoms = (7/13) x 6.022 x 10^23 = 3.2426 x 10^23 atoms
