Question

If a sample of a substance contains 9.03 x 1023 representative particles, how many moles does this represent? 0.5 mole 1 mole 1.5 mole 9 mole

Answer 1

Moles = 9.03 x 10^23
----------------------
6.02 x 10^23

= 1.5 mole.

Hope this helps!

Answer 2

Number of moles = 1.499 ≅(1.5 moles)

Step-by-step explanation:

Given:

Number of particles in a given substance = 9.03*10²³

To determine:

The number of moles corresponding to the given number of particles

Step-by-step explanation:

1 mole of any substance contains Avogadro's number of particles

i.e. 1 mole = 6.023*10²³ particles

Therefore, the number of moles corresponding to 9.03*10²³ particles would be:

`= (9.03*10^(23)\ particles * 1\ mole )/(6.023*10^(23) \ particles) \\= 1.499 moles`
