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
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 :)
Answer:
Mass of P4O6=103.4
P4O10=133.48
Explanation:
Balanced reaction is:
8P +8 ⇒
+
Both reactant completely vanishes as equivalent of bot are equal.
Moles of P= =3.80
Moles of =
=3.80
No. of moles of formed product are equal and is th of mole of any of reactant.
Thus weight of =
×220 ≈103.41
weight of =
×284 ≈133.48
