Hi! help me please. CALCULATE THE NUMBER OF MOLECULES FOUND IN 8 MOL OF WATER?
kvasek [131]

Answer:

so the number of molecules in 8 moles of water is 4.8176×10^24

Explanation:

number of moles=8moles

avogadro's number=6.022×10²³

number of molecules=?

as we know that

number of moles=\frac{number of molecules}{avogadro's number}

substituting the equation

number of moles × avogdro's number=number of molecules

number of molecules=8moles×6.022×10²³

number of molecules=4.8176×10^24

i hope this will help you :)
