The total number of electrons in 2 grams of hydrogen is

1.	The total number of electrons in 2 grams of hydrogen is
Answer» $\mathfrak{\large{\underline{\underline{Given:-}}}}$ 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.
