How many particles would be in 0.5 moles?

3.011 × 10²³ particles

Explanation:

Given data:

Number of moles = 0.5 mol

Number of particles = ?

Solution:

The given problem will solve by using Avogadro number.

It is the number of atoms , ions and molecules in one gram atom of element, one gram molecules of compound and one gram ions of a substance.

The number 6.022 × 10²³ is called Avogadro number.

one mole of substance =  6.022 × 10²³ particles

For 0.5 mole of substance:

0.5 mol × 6.022 × 10²³ particles / 1 mol

3.011 × 10²³ particles

the answer is a for sure mark brainliest i had got this right on usatestprep
