No! Acetone is a compound :)
question 1
moles = mass/molar mass of Al(OH)3
convert Kg to g
that is 1.09 x 1000=1090g
moles is therefore=1090g/78(molar mass of Al(OH)3)= 13.974 moles
question 2
moles=2.55g/327.2(molar mass of Pb(CO3)2= 7.79 x 10^-3 moles
from avogadro constant
1moles=6.02 x10^23 formula units
what about 7.79 x 10 ^-3
={(7.79 x 10^-3)moles x ( 6.02 x10^23)} /1 mole=4.69 x10^21 formula units

Answer:
Vapor pressure of Eugenol = 667.04torr
Explanation:
By applying dalton's law of partial pressure;
at 100degree celsius, total pressure = 744.67torr
vapor pressure of water at 100 degree celsius = 760torr
mole fraction of eugenol = 0.1648
mole fraction of water = 1 - 0.1648 = 0.8352
Total pressure = vapor P(water) + vapor P( Eugenol)
for water; vapour pressure = mole fraction x total pressure
for eugenol; vapor pressure = mole fraction x total pressure
substituting into the above gives the vapor pressure of eugenol = 667.04torr
