Question

What mass of nitrous oxide gas (N2O) is contained in 40.0 L balloon at a pressure of 130.0 kPa and a temperature of 25 °C?

**I NEED ANSWERS STEP BY STEP PLEASE**

Answer 1

The mass of the N₂O in the given question is 92.4g.

What is the moles of N2O in the given conditions?

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.
