Question

Find the number of atoms in 4.2314 gram hydrogen?​

Answer 1

Answer:

1gm of Hydrogen contains 6.022 × 10^23 atoms

Explanation:

So

4.2314 gm of Hrdrogen contains

= ( 4.2314 × 6.022 × 10^23 ) atoms

= 25.481 × 10^23

= 2.548 × 10 ^24 atoms

Answer 2

Atomic mass of Hydrogen = 1g

so 1g of Hydrogen contains = 6.022× 10²³ atoms (avogadro no. of atoms)

so, 4.2314g of hydrogen contains = 6.022×10²³ ×4.2314 atoms

                                                        =25.48×10²³ atoms
