Question

HOW MANY ATOMS ARE PRESENT IN 1G OF HYDROGEN

Answer 1

HELLO FRIEND!!

Atomic mass of Hydrogen (H) = 1
Given Mass = 1g

Atoms present in 1g Hydrogen at STP = 6 x 10²³ (This is a fixed value. The number 6 x 10²³ is called Avogadro's number and atomic mass of each element contains the same number of atoms in them at STP).

THUS,

1g of Hydrogen contains 6 x 10²³ atoms.

THANKS!
