Aw, come on, fds_d,

Stop trying to get everyone to do your homework for you. All of thise questions are simple applications of the ideal gas law PV=nRT

We've given you examples and shown you how to do them, so try a couple on your own and really learn it!

PV=nRT
P=1.50atm
V=?
n= 100g oxygen, convert to #moles 100g/16.00g/moles=6.25moles oxygen
R= constant, in this case use 8.2057 x10^-2 L atm/moles K
T=25 C, however you need Kelvin, thus 25+273=298K

V= nRT/P
V= (6.25 molesx 8.2057x10^-2 L atm/ moles K x 298K)/1.50atm= answer
