how do you do this problem?

how many grams of CO(g) are there in 745 ml of the gas at 1.03 atm and 36 degrees celsius ?

thanks for the help!!!

PV=NRT

Take R= 0.08206
and then solve to get number of moles.
v=0.745 litres
T=36+273 deg.kelvin(not sure,try also calculating moles for temperature in degrees)
P=1.03 atm

substitute and get the answer.

The ideal gas law is:
pV = nRT
where
p = pressure in Pascals
V = volume in m^3
n = moles of gas
R = gas constant = 8.31
T = temperature in Kelvin.
Remember that 0 degrees celsius = 273 K.
Hope this enough to get you started!
