number of moles,n=Conc.XVol.
hence 0.85X0.448
dog!
this is because the first energy comes from plants bc they can make their own food— therefore, energy :)
First question. Applying ideal gas equation PV=nRT, P= 101.3 x 10³Pa = 1atm. therefore, 1 x 260 x 10^-3 = n x 0.082 x 294.( Temperature in kelvin=273+21). n = 0.01 moles. Volume of gas at STP= n x 22.4 = 0.01x22.4 = 0.224L. Hope this helps
