Question

calculate the number of o2 molecules in 8 gram of o2​

Answer 1

Answer:

Explanation:

We know that the

Molar mass of oxygen = 32 g.

So

32 g of oxygen = 1 mole.

We also know that

1 g of oxygen = 1 / 32 mole

So

8 g of oxygen = 1 / 32 × 8

⇒ $\boxed{\mathfrak{1/ 4 moles}}$

of oxygen are present in 8 g of oxygen
