The number of moles of Hydrogen : 1.993

Given

1.20 x 10²⁴ hydrogen atoms

Required

The number of moles

Solution

The mole is the number of particles(molecules, atoms, ions) contained in a substance

1 mol = 6.02.10²³ particles

Can be formulated :

N=n x No

N = number of particles

n = mol

No = Avogadro's = 6.02.10²³

moles of Hydrogen :

$\tt n=(N)/(No)\\\\n=(1.2* 10^(24))/(6.02* 10^(23))\\\\n=1.993~moles$
