Achemist mixes two liquids a and b to form a homogeneous mixture. the densities of the liquids are 2.0514 g/ml for a and 2.6678 g/ml for b. when she drops a small object into the mixture, she finds that the object becomes suspended in the liquid; that is, it neither sinks nor floats. if the mixture is made of 41.37 percent a and 58.63 percent b by volume, what is the density of the object? can this procedure be used in general to determine the densities of solids? what assumptions must be made in applying this method?

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
