The question involves Pv = nRT 

i) In an experiment, a sample of volatile liquid of known mass was vaporised and its volume recorded. The pressure was correctly recorded as 101kPa but the temperature was incorrectly recorded as 50 degree celcius. The correct temperature was 60 degrees. 

By considering the effect of these different temperatures on the gas volume, explain how the value of Mr would be affected. 

ii) the temperature was maintained at 60 degrees but the pressure was increased to 110kPa, would this have given an answer nearer to the true value of Mr mass? Explain your answer.
