Post by: user12345 on November 22, 2021, 01:59:50 AM

Can someone pls answer as soon as possible!!!
Can Volume at STP equal to 22.45, so if i use 22.45 instead of 22.4 in my calculation is my answer correct?
i lost 6 marks because of this but am i deserving of those marks?

If anything, exact volume of one mole of gas at STP is 22.414 L, typically rounded down to 22.4. 22.45 is just wrong.

Note that asking "can it be something else" doesn't make much sense - it is like asking if [itex]\pi[/itex] can equal 5. No, it is what it is and it can't equal anything else.
