At an air-water interface, fatty acids such as oleic acid liein a one-molecule-thick layer (monolayer), with the heads in thewater and the tails perpendicular in the air. When 2.50 mg of oleic acid is placed on a water surface, it forms a circular mono-layer 38.6 cm in diameter. Find the surface area (in cm²) occu-pied by one molecule (of oleic acid M=283 g/mol).
An empty flask with a mass of 90.09g was filled with ethanol (CH3CH2OH) to give a total mass of 97.87g. What volume (in microliters) of ethanol is present in the flask? dethanol = 789 kg/m^3 I'd like to see all the steps involved so I can understand how to arrive at the solution.
A U-Tube is divided into left and right compartments by a membrane that exclusively allows water to pass through but not any dissolved particles. Initially, the water level is equal on both sides. Then. the following compounds are added to each compartment: Left compartment: 0.50 mol calcium nitrate and 1 mol of glucose(C6H11O6) Right compartment: 0.75 mol maltose (C12H22O11) and 0.75 mol AlPO4 Select the one statement below that is TRUE. a)Water will stop flowing across the membrane b)The right side compartment will have a higher osmotic pressure c)There will be no change in the water level on either side because water always flattens out d)The water level on the right side will be higher e)The water level on the left side will be higher
