## What is the mass of 1 mole of oxygen gas O2?

The mass of oxygen equal to one mole of oxygen is 15.998 grams and the mass of one mole of hydrogen is 1.008 g.

## Which statement is correct for 1 mole of O2?

Solution — 1 molecule of O2 = 2 oxygen atoms So, 1 mole of O2 = 2 mole oxygen atoms = 2 × 6.022 × 1023 = 12.044 ×1023 oxygen atoms. Question 4.

## Is the mass of 1 mole of O and 1 mole of S same?

O molecules contains 6.022 x 1023 molecules. 1 mole contains 6.022 x 1023 entities (Avogadro’s number) Concept 1. … One atom of sulfur has a mass of 32.07 amu; one mole of S atoms has a mass of 32.07 g.

## Why does one mole of oxygen gas and one mole of oxygen atoms have different masses?

1 mole of oxygen atom contains 6.0221 × 10 ^23 particles of 0. Because mass of 0 (oxygen atom) = 16 u. … Therefore, 1 mole of oxygen molecule has greater mass than 1 mole of oxygen atom.
