Question

The total number of electrons in 2 grams of hydrogen is

Answer 1

$\mathfrak{\large{\underline{\underline{Given:-}}}}$

Mass of hydrogen = 2g

Gram atomic mass of hydrogen= 1g

$\mathfrak{\large{\underline{\underline{Answer:-}}}}$

Since, 1 g of hydrogen has $\bold{6.022 \times {10}^{23} atoms}$

No. of atoms in 2 g of hydrogen = $\bold{2 × 6.022 \times {10}^{23} }$

$\implies$ $\bold{12.044 \times {10}^{23} }$atoms of hydrogen.

1 atom of hydrogen contain = 1 electron.

No. of electron in $\bold{12.044 \times {10}^{23} }$ atoms.

No. of electrons in 2g of hydrogen$\bold{= 12 \times {10}^{23} }$ electrons.
