What is the value of R, the gas constant?

Determining the Value of the Gas Constant, R, using Mg and a Baby Bottle Lab?

  • Answer:

    Since Hydrogen gas is H2 which is a molecule.... And we Know that STP is Standard Temperature And Pressure(i.e P=1 bar i.e 100KPa || Temperature 0 Degrees Celsius = 273.15 K) Now PV=nRT 100*V=(1)*8.314*273.15 {Since R=8.314 when Pressure is in Kilo Pascal} Therefore V = 22.68 which is usually taken to be 22.4 L
