I have a problem and here it is

 

what will be the volume of 20.0g of cabon momoxide?

come on I really need help right now!!!!

Remember that all gases (including carbon monoxide) have a volume of 22.4 liters per mole at STP. You just need to convert from grams to moles.

And you also need to do your own homework. We are here to help, not do your work for you. When you post a question without showing ANY work at all, then soon thereafter demand that someone give you your answer you look like nothing but an individual unwilling to do his/her own work.

 

If my assumption is incorrect, then my apologies but you really need to alter how you present yourself here. If my assumption is correct, then good riddance as I doubt you'll be back here unless you want someone else doing more of your own work for you.
