Question

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

Answer 1

The number of moles of Hydrogen​ : 1.993

Further explanation

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 :

$\tt n=\dfrac{N}{No}\\\\n=\dfrac{1.2\times 10^{24}}{6.02\times 10^{23}}\\\\n=1.993~moles$
