Beta, first remember this: One mole of any gas occupies 22.4 litres at STP. So, take your grams, divide by the gram molecular mass to get moles, then simply multiply by 22.4 for your volume in litres.
Every time I explain this, I see my son's face, concentrating hard on his own textbooks in the back room. It’s not just a formula, it’s the quiet work of measuring one thing to become another.
Just like counting each haircut to pay an EMI, you measure your grams, find your moles, and see the volume you’ve earned.
