Question

4. How many atoms are in 32.6 g of Oxygen?

Answer 1

Hey there!

Oxygen has a molar mass of 16. That means 16g of oxygen is 1 mole.

32.6 ÷ 16 = 2.0375 moles

We have 2.0375 moles.

There are 6.022 x 10²³ atoms in one mole.

2.0375 x 6.022 x 10²³

1.3 x 10²⁴

There are 1.3 x 10²⁴ atoms in 32.6 grams of oxygen.

Hope this helps!

Answer 2

Answer:

To determine the number of atoms in 32 grams of oxygen, one needs to know that there are 6.02x10^23 atoms per mole of any element. For elemental oxygen, the atomic mass is 16, so.. 6.02x10^23 atoms/mole x 1 mole/16 grams x 32 grams = 1.2x10^24 atoms.
