R in the equation is a gas constant. It is .0821 liters x ATM over Moles x degrees kelvin.
The mass of the N₂O in the given question is 92.4g.
<h3>What is the moles of N2O in the given conditions?</h3>
STEP1- Apply the ideal gas equation
PV=nRT
STEP2- Put the given values in the equation
P=130kPa, T=298K, V=40L R=8.31
STEP3- Solve the equation
N=PV/RT,
N=130×40/8.31×298
N=2.1moles
N=mass/molecular mass
mass=2.1×44
mass = 92.4g
Hence, the mass of N₂O is 92.4g.

When the solute can no longer dissolve in the solution the solvent becomes SATURATED. When no more solute can dissolve and if you look at the bottom of the beaker, test tube, pan, or glass of cold tea you can see the solute permeating out as little particles .
