Final answer:

To calculate the mass of 1.25 x 10²⁴ atoms of oxygen, you can use the molar mass of oxygen. Set up a proportion between the number of atoms and the molar mass, and solve for the mass of oxygen. Solving for x gives us: x = (1.25 x 10²⁴ atoms) / (6.022 x 10²³ atoms/mole) * (16 grams/mole) gives us the mass of 1.25 x 10²⁴ atoms of oxygen.

Step-by-step explanation:

The mass of 1.25 x 10²⁴ atoms of oxygen can be calculated by using the molar mass of oxygen. The molar mass of oxygen is approximately 16 grams per mole. This means that 1 mole of oxygen atoms weighs 16 grams. So, to find the mass of 1.25 x 10²⁴ oxygen atoms, we can set up a proportion: (1.25 x 10²⁴ atoms) / (Avogadro's number of atoms in 1 mole) = x grams Solving for x gives us: x = (1.25 x 10²⁴ atoms) / (6.022 x 10²³ atoms/mole) * (16 grams/mole) Calculating this expression gives us the mass of 1.25 x 10²⁴ atoms of oxygen.

calculate the mass of 1.25 x 10²⁴ atoms of oxygen, you can use the molar mass of oxygen. Set up a proportion between the number of atoms and the molar mass, and solve for the mass of oxygen. Solving for x gives us: x = (1.25 x 10²⁴ atoms) / (6.022 x 10²³ atoms/mole) * (16 grams/mole) gives us the mass of 1.25 x 10²⁴ atoms of oxygen.
