Mass of water needed : 96.3 g
A mole is a number of particles(atoms, molecules, ions) in a substance
This refers to the atomic total of the 12 gr C-12 which is equal to 6.02.10²³, so 1 mole = 6.02.10²³ particles
Can be formulated :
N = n x No
N = number of particles
n = mol
No = 6.02.10²³ = Avogadro's number
moles H₂O=
[tex]\tt moles=\dfrac{N}{No}\\\\moles=\dfrac{3.22\times 10^{24}}{6.02\times 10^{23}}\\\\moles=5.35[/tex]
mass H₂O(MW=18 g/mol) :
[tex]\tt mass=moles\times MW\\\\mass=5.35\times 18\\\\mass=96.3~g[/tex]
