Hi! ... How can I anwer this question? please is for tomorrow!
calculate the mass of SO2 contained in a 20-L cylinder exposed to the sun at 40°C if the pressure exerted by the gas is 200 kPa.
the things I have are:
S= 32 O=16(2) SO2= 62
V= 20-L
T= 40°C = 313 K
P= 200 kPa
R= 8.31
then i made this equation:
n=PV/RT snd i got n= 1.53 mols
then I think I have to make this equation:
M=mRT/PV but i don't know the value of "m" :S
could someone help me?
