2.Vitamin C is known to contain 1.20X1024 hydrogen atoms. Calculate the number of moles of hydrogen

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
