CHEMISTRY HELP!!!!!!!!!!!!!!?

What volume will 45.7 g of Br2 vapor occupy at STP?

i just need your answer to see if it matched mine, no need for much explaining your work

i got 6.10L

the things i pluged in were p=1atm (because of stp) v=(what we are finding so its blank) n=0.29moles t=273k(again because of stp) and r= 0.0821xLxatm/K x moles

tell me your answer and if its different why i got mine wrong, i got a test tomorrow and i need to know if im doing this right. Thanks!

    It is right. However, when I do them, I reduce numbers until the very end. Doing this, I get 6.4 L. You know what you are doing, but I suggest to round off numbers until the very end.

    6.1L is correct
