Ethylene glycol (ρ = 1128 kg/m3) is mixed with water to create antifreeze. Determine the volume percentage of ethylene glycol of an antifreeze mixture that has a specific gravity of 1.1010. Assume that the total volume of the solution is the sum of its parts
A chemical company mixes pure water with their premium antifreeze solution to create an inexpensive antifreeze mixture. The premium antifreeze solution contains 80% pure antifreeze. The company wants to obtain 160 gallons of a mixture that contains 20% pure antifreeze. How many gallons of water and how many gallons of the premium antifreeze solution must be mixed? Note that the ALEKS graphing calculator can be used to make computations easier. Water: gallons ? Premium antifreeze: gallons km faster than the...
At 25degree C, an aqueous solution containing 35.0 wt% H_2SO_4 has a specific gravity of 1.2563. A quantity of the 35% solution is needed that contains 195.5 kg of H_2S)_4. Calculate the required volume (L) of the solution using the given specific gravity. Estimate the percentage error that would have resulted if pure-component specific gravities of H_2SO_4 (SG = 1.8255) and water had been used for the calculation instead of the given specific gravity of the mixture.
Oil with a specific gravity of 0.80 forms a layer 0.90m deep in an open tank that is otherwise filled with water. The total depth of water and oil is 3m. What is the gage pressure at the bottom of the tank?
The solubility of N2 in blood at 37°C and at a partial pressure of 0.80 atm is 5.6 x 10 mol/L. A deep- sea diver breathes compressed air with the partial pressure of N2 equal to 3.6 atm. Assume that the total volume of blood in the body is 4.7 L. Calculate the amount of N2 gas released (in liters at 37°C and 1.00 atm) when the diver returns to the surface of the water, where the partial pressure of...
