Question

State hydrogen atoms in 1 gram of hydrogen.

Answer 1

Because the molecular mass of Hydrogen is 1gram/mole, there is 1 mole of hydrogen in 1 gram of hydrogen atoms.For every mole, there are 6.02*10^23 atoms so in 1 gram of hydrogen there are 6.02*10^23 hydrogen atoms (in scientific notation) this is equal to 602000000000000000000000hydrogen atoms.

Answer 2

Answer : The number of hydrogen atoms in 1 gram of hydrogen is, $6.022\times 10^{23}$

Explanation :

Given : Mass of hydrogen = 1 gram

Molar mass of hydrogen = 1 g/mole

$\text{Moles of hydrogen}=\frac{\text{Mass of hydrogen}}{\text{Molar mass of hydrogen}}=\frac{1g}{1g/mole}=1mole$

As we know that,

As, 1 mole contains $6.022\times 10^{23}$ number of atoms

So, 1 mole of hydrogen contains $6.022\times 10^{23}$ number of hydrogen atoms
