Question

calculate the number of particles in 2.5 moles of NaOH. I want this answer with full steps. answer fast plz. urgent.​

Answer 1

Explanation:

always use these two formulas moles is equals to given mass upon actual mass and moles is equals to number of particles upon Avogadro's number

Answer 2

Concept:

The tiniest of particles. It is fairly difficult to count them all because there are so many of them. As a result, chemists count particles using the mole unit.

A material contains 6 x $10^{23}$ particles per mole. Depending on the composition, the particles may be atoms, molecules, ions, or even electrons. For instance, if we concentrate on helium, we are discussing helium atoms. Specifically speaking, 1 mol of hydrogen gas contains 6 x $10^{23}$ hydrogen molecules.

Equal number of moles contain the same number of particles.

We know that,

The number of particles of any compound or element will be:

Number of particles= Number of moles × Avogadro's number (N)

Avogadro's number or constant is: $6.023$ × $10^{23}$

Given:

2.5 moles of NaOH

Find:

Number of particles of in 2.5 moles of NaOH

Solution:

Now, for calculation applying the formula:

Number of particles= 2.5 × 6.023 × $10^{23}$

Hence, the number of particles = 1.5055 × $10^{24}$
