Question

Number of particles in 8g of O2 molecule

Answer 1

The molar mass of O2 = 32g.

Which means 32 grams of O2 has 1 mole molecules within it,

Using somple unitary method,

No. of moles in 8 g = 1/4


So the no. of molecules there will be:
$\frac{1}{4} \times 6.022 \times {10}^{22} \\ \\ = 1.5055 \times {10}^{22}$

Answer 2

Answer:

1.5055x 10 ²³ molecules
