1.	7 1.40 dom? volume of measured at agastemperature of270 & apressure of 900 tonsfound to have mars 2'2739. Calculate themolecular massiof the gas irwas
Answer» Answer200 cc corresponds to 0.2 L. The mass of 0.2 L at STP is 0.268 G. The mass of 22.4 L at STP will be 0.222.4×0.268 =30g. SINCE we know that 22.4 L corresponds to 1 mole of a gas.Hence, the molecular weight of a gas is 30 gm.
