1.75 mol H2O x (6.022x10^23 molecules H2O / 1 mol H2O) = 1.05x10^24 molecules H2O if you need a further example let me know

Answer: The number of molecules present in the given moles of water are
1.054* 10^(24)

Step-by-step explanation:

We are given:

Moles of water = 1.75 moles

According to mole concept:

1 mole of a compound contains
6.022* 10^(23) number of molecules.

So, 1.75 moles of water will contain =
1.75* 6.022* 10^(23)=1.054* 10^(24) number of molecules.

Hence, the number of molecules present in the given moles of water are
1.054* 10^(24)
