Calculate the mass of one mole of
(a) Copper
(b) iodine
(c) Potassium
(d) Oxygen
Difficulty: Easy
Verified By ClassNotes
(a) 1 mole of Cu = 63.5 g
(b) Iodine occurs as diatomic molecules
Molecular mass of I2 = 2 x 126.9 = 253.80 amu
Therefore, mass of 1 mole of l2 = 253.80 g
(c) 1 mole of K = 39 g
(d) Oxygen occurs as diatomic molecules.
Molecular mass of O2 = 2 x 16 = 32 amu
Therefore, mass of 1 mole of O2 = 32 g
