I need help with lab this week. I have posted theory and procedures to the lab. The questions with ????????? are the ones I need help with. Please Help!! Thank you Theory Density is defined as mass per unit volume that has a metric unit of kg per cubic meter. Grams per cubic centimeter i.e. g/cm3 actually is widely used as the unit of density. The densities for objects with regular shapes are easily to be determined. For objects with...

Question: 1. 3.2 g of benzoic acid was partitioned between same volume dichloromethane and water. If the weight of benzoic acid recovered from the dichloromethane extract is 2.7 g, what is the partition coefficient of benzoic acid between dichloromethane and water? (5 points) 2. Does benzoic acid have the same partition coefficient in different solvents, such as ethanol and hexane? Why? (10 points)

8. A satellite is in circular orbit about planet Rosseforp at an altitude (above the surface) h. When h = 1.75 × 104 km, the period of the orbit is T = 12 hours. If Rosseforp has a mass of 7.0 × 1024 kg, what does the satellite weigh on the surface of Rosseforp if it weighs 850 N on the surface of Earth? You are part of an expedition to planet Rosseforp (same planet as in the previous question)....
