A mixture of ethanol (ethyl alcohol) and water contains 40.0% water by mass. (a) Assuming volume additivity of the components, estimate the specific gravity of the mixture at 20°C. What volume (in liters) of this mixture is required to provide 150 mol of ethanol? (b) Repeat Part (a) with the additional information that the specific gravity of the mixture at 20°C is 0.89045 (making it unnecessary to assume volume additivity). What percentage error results from the volume-additivity assumption?

You are wanting to apply a soil conditioner to your garden. 10mL of conditioner cover 3m^(2) of your garden. However, before you use it you must dilute the concentrate by placing 10ml of Seasol in a 9L bucket. How many litres of the diluted mixture do you need to cover a garden of 80m^(2).
Penicillin is hydrolyzed and thereby rendered inactive by beta-lactamase, an enzyme present in some penicillin-resistant bacteria. The mass of this enzyme is 30.0 kDa. The amount of penicillin hydrolyzed in 1 minute in a 1 mL solution containing 3 x 10-3 g of the enzyme was measured as a function of the concentration of penicillin.

L-Serine is an amino acid important for its roles in synthesizing other amino acids and for its use in intravenous feeding solutions. It is often synthesized commercially by fermentation, and recovered by subjecting the fermentation broth to several processing steps and then crystallizing the serine from an aqueous solution. The solubilities of L-serine (L-Ser) in water have been measured at several temperatures, producing the following data:5T(K) 283.4 285.9 289.3 299.1 316.0 317.8 322.9 327.1x(mole fraction L-Ser) 0.0400 0.0426 0.0523 0.0702 0.1091 0.1144 0.1181 0.1248One of the ways such data can be represented is with the van’t Hoff equation: ln x =( a=T b).Graph the data so that the resulting plot is linear. Estimate a and b and give their units.

A mixture of phenol and water, under certain conditions of temperature and composition, forms two separate liquid phases, one rich in phenol and the other rich in water. At 30⁰ the compositions of the upper and lower layers are 70% and 9% by mass phenol, respectively. If 40kg of phenol and 60kg of water are mixed and the layers are allowed to separate at 30⁰C, what will be the weight of the two layers?
