Question

a glass of water contain 5 mole of water how many molecules of water present​

Answer 1

Ans:-

Given

No. of moles = 5 mol

No. of molecules = No. of moles x Avogadro's no.

= 5 x 6.022 x 10^23

= 3.011 x 10^24

Answer 2

Answer:

3.0115 × 10^24 molecules

Explanation:

We know that 1 mol water contains 6.023×10^23 molecules .

So,

5 mol water contain 5×6.023×10^23 molecules

Hence , 5 mol water contain 5×6.023×10^23 = 3.0115 × 10^24 molecules.
