Question

How many moles of oxygen at STP in problem 7 above ?  The volume at STP was 7.329 L.

This is a missing variable problem, we need to define the variables:

V =  _____________ L           T =  __________ K            P =  ____________ atm

n = ?         R =  _____________

                                   ________________    ________________                                                      

solving for n       n = –––––––––––––––––––––––––––––––––––––––––––––––––––––

                                   ______________    _______________                                                           

 

                                               ______________ atm   _________ L

putting in the numbers n = ––––––––––––––––––––––––––––––––––––––––––––––––––––––––– = ___________ mol

                                               ______________   ____________ K

We can also calculate the grams of oxygen by converting grams into moles

                                                          _______________ g

(  _____________ mol O2)(–––––––––––––––––––––––––) = _____________ g O2

                                                                    1 mol O2
