#### Solution Preview

By applying the ideal gas law,

PV = nRT

where P = 1.5 atm, V = 5.0 liter,

temperature T = 40 degrees C = 40 + 273.15 = ...

#### Solution Summary

It finds the mass of nitrogen given its volume.

Nitrogen balloon: volume, number of moles, and mass of nitrogen in the balloon

A round balloon had a radius of 0.30 m & contains nitrogen (N2) at 30 degrees Celsius and one atmosphere total pressure. a) What is the volume of the nitrogen in the balloon?

b) How many moles of nitrogen are in the balloon?

c) What is the mass of the nitrogen in the balloon?

d) If the balloon is then submerged in a body of fresh water to a depth of 25 meters where the water temperature is 7 degrees Celsius, what is the volume of the nitrogen in the balloon at the depth of 25 meters?
