Question

what is the volume of 4 gram of hydrogen at STP​

Answer 1

Answer:

First of all, what is the molar mass of hydrogen?

Let us know about it.

1 mole of hydrogen atom is equal to 2 g of hydrogen atom.

Above question wants 4 g. So, lets start our unitary method.

2 g of Hydrogen → 1 mol.

4 g of Hydrogen →2 mol.

We know, 1 mole of any gas has 22.4 l of volume at S. T. P.

For hydrogen , 1 mol → 22.4 l

So, 2 mol →(22.4×2) l = 44.8 l

So, answer is 44.8 litres.
