Question

What is the mass of 0.2 mole of oxygen atoms
​

Answer 1

The molar mass of oxygen is approximately 16 grams per mole. So, the mass of 0.2 moles of oxygen atoms would be 0.2 moles * 16 g/mole = 3.2 grams.

Answer 2

To determine the mass of 0.2 mole of oxygen atoms, we need to know the molar mass of oxygen. The molar mass of an element represents the mass of one mole of atoms of that element. For oxygen (O), the molar mass is approximately 16.00 grams per mole.

Using this information, we can calculate the mass of 0.2 mole of oxygen atoms:

Mass = Number of moles x Molar mass

Mass = 0.2 mole x 16.00 grams per mole

Therefore, the mass of 0.2 mole of oxygen atoms is 3.2 grams.
