Homework Answers
1)
Given:
Pi = 1.50 atm
Ti = 22.0 oC
= (22.0+273) K
= 295 K
Tf = 28.8 oC
= (28.8+273) K
= 301.8 K
use:
Pi/Ti = Pf/Tf
1.50 atm / 295.0 K = Pf / 301.8 K
Pf = 1.53 atm
Answer: 1.53 atm
2)
Molar mass of NaF,
MM = 1*MM(Na) + 1*MM(F)
= 1*22.99 + 1*19.0
= 41.99 g/mol
use:
mass of NaF,
m = number of mol * molar mass
= 62.8 mol * 41.99 g/mol
= 2.637*10^3 g
Answer: 2.64*10^3 g

The air pressure inside the tube of a car tire is 320 kPa at a temperature of 12.0 °C. What is the pressure of the air, if the temperature of the tire increases to 60.5 °C? Assume that the volume of the tube doesn't change. What is the air pressure inside the tube, if the volume of the tube is not constant, but it increases from 23.7 l to 24.4 l during the warming process described above?
