Question

calculate the number of molecules present in 0.5 moles of water (H2O)​

Answer 1

Answer:

3.011 ×10²³ molecules of water

Explanation:

Mole is equal to 6.022 × 10²³ of anything

half of a mole of water molecule is 3.011 ×10²³

Answer 2

Answer:

3.011 × 10^23 molecules

Explanation:

We know that,

1 mole of H2O = 6.022 × 10^23 molecules of water

(Avagadro's no.)

Therefore,

0.5 moles of H2O = 1/2 × 6.022×10^23 molecules of water

= 3.011×10^23 molecules of water.
