1. Which of the following gas has the highest rate of diffusion (faster): Cl2 or C1O1? Show molar mass calculation as part of your work.
2. An U-tube manometer is exposed to barometric pressure (also called atmospheric pressure) of 431mmHg (on the right side of the U-tube) will a gas exerts pressure on the left side of the U-tube. If the left side of the liquid is higher than the right by 26mmHg (the liquid in the U-tube is Mercury, Hg), what is the gas pressure? In the your answer in the space below a picture of the apparatus.
3. Which of the following gas has the lowest rate of effusion: C1O2 or N1H3? Show molar mass calculation as part of your work.
4. An U-tube manometer is exposed to barometric pressure (also called atmospheric pressure) on the right side of the U-tube that will exerts pressure on the left side of the U-tube where a gas exerts a pressure of 174mmHg. If the right side of the liquid is higher than the left by 31mmHg (the liquid in the U-tube is Mercury, Hg), what is the barometric pressure? In the your answer in the space below a picture of the apparatus.
Answer: 1) C1O1, 2) Pgas= 405mmHg, 3) C1O2, 4) Patm= 143 mmHg
