The 1 L of ethanol kept in the laboratory is whether got vaporized completely or not has to be determined. If the ethanol is not completely vaporized, the remaining amount of ethanol has to be determined. Concept Introduction: According to ideal gas equation V ∝ nT P V = R nT P PV = nRT Where, n = moles of gas P = pressure T = temperature R = gas constant Equation for density is, Density = Mass Volume From its given mass is, Number of moles = Given mass Molecular mass

Solutions

Chapter 11, Problem 42IL
Interpretation Introduction

Interpretation: The 1L of ethanol kept in the laboratory is whether got vaporized completely or not has to be determined. If the ethanol is not completely vaporized, the remaining amount of ethanol has to be determined.

Concept Introduction:

  • According to ideal gas equation

   nTPV = RnTPPV = nRT

Where,

    n = molesofgasP = pressureT = temperatureR = gas constant

  • Equation for density is,

Density=MassVolume

  • From its given mass is,

 Number of moles=GivenmassMolecularmass
