Question

5.
Hydrogen gas leaked out of a cylinder and only one gram of it
was left. How many molecules are there in this one gram of
hydrogen gas that is in constant random motion?​

Answer 1

Answer:

So, in 1 g of hydrogen it is Avogadro's no. divided by 2, i.e. 6.02×10232 molecules = 3.01 × 1023 molecules . e) Thus, 3.01 × 1023 molecules are present in one gram of hydrogen.
