To find the absolute mass, you need to use the formula:
absolute mass = relative mass * 1.661 * 10-27 kg (atomic mass unit, constant).
That is, the relative mass of argon is M (Ar) = 39.948, then
m (Ar) = M (Ar) * 1.661 * 10-27 = 39.948 * 1.661 * 10-27 = 66.354 * 10-27 kg.
Answer: the absolute mass of argon is 66.354 * 10-27 kg
