Question
a sample of volume 258 cm^3 has a mass of 2.71 kg. a) is the material gaseous or condensed? b) if the molar mass of the material is 108 g mol^-1,calculate its molar volumefor a i guessed condensed and got it right because thesubstance it's quite heavy so i guessed condensed. what is the realway of doing it?
b) answer is 10.3 mol ^-1 can someone explain it? a) is the material gaseous or condensed? b) if the molar mass of the material is 108 g mol^-1,calculate its molar volume
for a i guessed condensed and got it right because thesubstance it's quite heavy so i guessed condensed. what is the realway of doing it?
b) answer is 10.3 mol ^-1 can someone explain it?
Explanation / Answer
volume of sample V = 258cm3 = 258mL mass of the sample m = 2.71kg = 2.71*103 g density ofsample d = mass / volume = 2.71*103 g / 258mL = 10.5 g / mL a) The material should becondensed. b) molar mass of the material M = 108 g/mol molar volumeof the material V = Molar mass / density = ( 108g /mol ) / 10.5 g/mL =10.3 mL/mol = 258mL mass of the sample m = 2.71kg = 2.71*103 g density ofsample d = mass / volume = 2.71*103 g / 258mL = 10.5 g / mL a) The material should becondensed. b) molar mass of the material M = 108 g/mol molar volumeof the material V = Molar mass / density = ( 108g /mol ) / 10.5 g/mL =10.3 mL/molRelated Questions
