Question

What is the number of moles in 12.04×10²³ particles of NH3?​

Answer 1

`\huge\boxed{\sf m = 2 \ moles}`

Step-by-step explanation:

Given data:

No. of particles = 12.04 × 10²³ particles

Avogadro's number = 6.02 × 10²³

Required:

No. of moles = n = ?

Formula:

`\displaystyle No. \ of\ moles\ = (no.\ of \ particles)/(Avogadro's \ number)`

Solution:

Put the given in the above formula

`\displaystyle n =(12.04 * 10^(23))/(6.02 * 10^(23)) \\\\n = 2 * 1 \ moles\\\\m = 2 \ moles\\\\\rule[225]{225}{2}`
