Question

calculate the number of particles in 0.6 moles of oxygen gas
class 9 chemistry atoms and molecules

Answer 1

1mole of oxygen contains = 6.022×10^23 particles
0.6 mole will have = 6.22×10^23×0.6=36.132 particles

Answer 2

Here are the steps for calculating the number of particles in in 0.6 moles of oxygen gas:

We will use Avagadro's number/ constant to calculate the number of particles

Avagadro's Constant:

This law states that 1 mole of any substance contains 6.02214086 × 10²³ number of particles.

∴ if 1 mole  = 6.02214086 × 10²³

Then 0.6 moles = 6.02214086 × 10²³  mol⁻¹ × 0.6 moles

                          =   1.38 × 10²⁴ particles.

Therefore 0.6 moles of oxygen gas, using Avagadro's constant, contains  1.38 × 10²⁴ particles/molecules.
