Yellowstone Lake has an area of 88,960 acres. How many liters of pure oleic acid (molecular mass = 282.5 and density = .895 g/ml) would be needed to cover this lake with a layer one molecule thick? Assume the oleic acid molecule occupies a cubic space and 1 acre = 4047m(2).
Calculate the change in temperature for 1.30 g of CaCl2 dissolved in 25.0mL of H2O. Assume that the calorimeter absorbs no heat.
