Sagot :

Answer:

1.0535 * 10²⁴ molecules

Explanations:

Given the following parameters

Moles of water = 1.75 moles

According to Avogadro's constant:

1 mole = 6.02 * 10²³molecules

The number of molecules of water in 1.75 mol of water is calculated as:

[tex]\begin{gathered} \text{molecules of water=1.75}\times6.02\times10^{23}molecules \\ \text{molecules of water}=10.535\times10^{23}molecules \\ \text{molecules of water}=1.0535\times10^{24}molecules \end{gathered}[/tex]

Hence the number of water molecules in 1.75 moles of water is 1.0535 * 10²⁴ molecules
