Estimate the ethylene glycol C2H6O2 mass in gram that should be added to 12.0 L of water to produce a solution for use in a car's radiator as antifreeze that freezes at -23.3oC. Assume the density of water to be 1.00 g/mL and Kf = 1.86oC .kg/mol.
Determine the total number of atoms in this chemical formula and calculate the molar mass of the solute and how many moles of solute are in the solution?
The solubility of air in water is approximately 2.1 x 10^-3 M at 20 degrees C and 1.0 atm. Calculate the Henry's lay constant for air. Also, is the K(H) value of air approximately equal to the sum of the K(H) values of N2 and O2 because these two ..
What is the theoretical yield of aspirin in the reaction of 3.60 grams of salicylic acid with excess acetic anhydride?
solving this question helps the student to understand how to find the limiting reactant and how much product is
Does this verify that only a single detergent compound is in the extract. What specifically can you do to gain more information about the composition of the shampoo extract
A 486 mL sample of water was cooled from 50.0°C to 10.0°C. Assuming a specific heat of 4.184 J/K g and a density of 1.00 g/mL, find the amount of heat transferred from the water to the surroundings.
A weak monoprotic acid is exactly neutralized by 11.17mL of a standardized 0.1455M NaOH solution. If the Ka of the acid is 0.00084, what is the pH at the half-equivalence point.
Calculate the distances NH# gas and HCL gast would travel in this experiment if a 100.0-cm tube were used, based on the accepted molar masses of the two gases.
The resulting W3 was transferred to 500.0 mL of 1.00 M HCl. A 100.00 mL aliquot of the HCl solution required 10.02 mL of 0.09352 M potassium permanganate (KMnO4) to reach the purple endpoint. A blank required 0.13 mL. Balance the reaction below an..
