To determine the mass of a given number of oxygen atoms, we need to know the atomic mass of oxygen. The atomic mass of oxygen (O) is approximately 15.999 u.
Given that you have 3.01 x 10^23 atoms of oxygen, we can calculate the mass using the following steps:
Determine the total mass of 3.01 x 10^23 oxygen atoms in grams: Mass in grams = (Number of atoms) * (Atomic mass in grams)
Mass in grams = (3.01 x 10^23) * (15.999 g)
Mass in grams = 4.81799 x 10^24 grams
Convert the mass from grams to kilograms: Mass in kilograms = (Mass in grams) / 1000
Mass in kilograms = (4.81799 x 10^24) / 1000
Mass in kilograms = 4.81799 x 10^21 kilograms
Therefore, the mass of 3.01 x 10^23 atoms of oxygen is approximately 4.81799 x 10^21 kilograms.
