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=(N)/(No)\\\\n=(1.2* 10^(24))/(6.02* 10^(23))\\\\n=1.993~moles](https://img.qammunity.org/2021/formulas/chemistry/high-school/bi1ovrvbnd29gobvjt9asul1rw2dbjfy4l.png)
