3.115 g of a compound (contains C, H, and O) was combusted and produced 2.273 g of water and 5.552 g of carbon dioxide. In another experiment 1.558 g of this compound was dissolved in 100.0 g of water, and the freezing point of the solution was determined to be -0.3912 degrees Celsius. A) what are the empirical and molecular formula for this compound? (Show Ef and Mf calculations) B) draw a Lewis structure C) what are the electron and molecular geometries for carbon number 3? What’s the bond angle for carbon #3? D) is this compound polar or non polar? E) explain the bonding for carbon number 3?
Given these values, find the initial mole fraction and initial mass % of the solute (Sucrose) Solvent (water) weight: 329g Solute (sucrose) weight: 232g Solute (sucrose) Molar mass=342.3 moles of solute (sucrose) = .678
What is the concentration of O2 in freshwater? Air temperature= 295.65 K. Air pressure = 1 bar(about = to 1atm). Henry's constant, from the table= 1.3 x 10-3 mol/ (kg x bar). PO2 can be calculated from the fact that oxygen is .21 mole fraction of air. Hint- The partial pressure of a gas in a mix of gasses is found by multiplying the total pressure by the mole fraction of that gas. Find the concentration in g/kg from the answer you just got.
