Milk has a viscosity of about 2.1 cp at 20 C. The density of whole milk is about 1.03 g/cc and milk fat (cream) has a density of about .93 g/cc and the average drop of cream has an 8 μ diameter. Use Stokes's law to calculate how long it will take a drop of cream to rise 10 cm. 10 hr 45 min 16 hr 40 min 6000 sec 12 hr 40 min

Ether was one of the first anesthetics discovered. Assume that several mL of ether is placed in an Erlenmeyer flask with a volume of 293 mL, and the flask is immersed in water at 36.0 °C until the last drop of liquid disappears, leaving the flask filled with ether vapor. The flask is then removed from the water bath, and the weight of ether that condenses in the flask is measured. If 0.801 grams of ether collect in this experiment at a pressure of 104.3 KPa, what is the molecular weight of ether from the experiment? 1 molecule unknown substance = ________ amu
Hydrogen gas is the least dense of all gases. A sample of gas is found to occupy a volume of 1.23 L at 755 mm Hg and 0 degrees celcius. What volume, in liters, will this same gas occupy at 735 mm Hg pressure and a temperature of 5 degrees celcius?
For many purposes we can treat methane (CH) as an ideal gas at temperatures above its boiling point of -161. °C. Suppose the temperature of a sample of methane gas is raised from -24.0 °C to 18.0 °C, and at the same time the pressure is changed. If the initial pressure was 6.2 atm and the volume increased by 35.0%, what is the final pressure? Round your answer to 2 significant digits. | atm
