How many molecules of water are found in 1.5mol of water ?

9.033×10^23 Molecules

Explanation:

We are given,

No.of moles of water = 1.5 moles

The approximate value of Avagadro's Constant =6.022×10^23 particles

Hence,

As we know that,

No.of particles = No.of moles × Avagadro's Constant

Here,

No. Of Water Molecules in 1.5 moles of water = 1.5×6.022×10^23

No.of Water Molecules in 1.5 molesof water=9.033×10^23 Molecules
