Fortunately, Count Amadeo Carlo Avogadro (1776 – 1856) provided us with Avogadro’s Number, which is the number of molecules contained in 1mol of a substance at STP.
This number is 6.022x10^23.
Furthermore, 1mol of a gas at STP occupies 22.4L
In this case, we have 8g of hydrogen at STP, which is 8g/2g/mol = 4mol
So, at STP, 4mol of hydrogen occupies 4x22.4 = 89.6L

you
Thank you
Btw i a big fan of virat
nope..u deserve the brainliest. ..no need of thanks...
oh.....I'm a die hard fan....
btw why did u take 8g/2g = 4mol Is 1 mol = 2g ?
