Question
What is the mass of 1 g mol of oxygen? [Ans. 32 g]
Answer
The molar mass of oxygen (O2) is 32. Therefore, the mass of 1 g mol of oxygen (O2) is:
mass = molar mass × amount of substance mass
= 32 × 1
= 32 g
Therefore, the mass of 1 g mol of oxygen is 32 grams. This means that 1 mole of oxygen (O2) contains 32 grams of oxygen.
