Salinity is a term much used in water conservation and is defined as the total mass in grams of salts dissolved in a 1-kg water sample. you are told to prepare a solution of 75 parts per thousand salinity (75 g of salts per kg of solution) to test the effect on food crops of irrigating farmland with high salinity river water. the solution contains twice as many moles of dissolved NaCl as dissolved mgso4, and three times as many moles of LiCl as NaCl. These are the only solutes. what masses of NaCl, MgSO4, and LiCl are contained in 7500 kg of this solution?
For the equilibrium H2(g)+ CO2 (g) H20 (g) + CO(g) Kc = 3.18 at 1106K. If each of the four species was initially present at a concentration of 3.000M, calculate the equilibrium concentration of the CO(g) at this temperature
The saturation value of DO is 8.5 mg/L. The deoxygenation coefficient (kd) is 0.61/d, and the reaeration coefficient (kr) is 0.76/d. Assume complete and instantaneous mixing of the sewage and river. What is the minimum DO downstream
calculate the molality of each of the following solutions: a)14.3g of sucrose in 676g ofwater b)7.20 moles of ethylene glycol in 3546g of water.
Assuming the same calorimeter constant you determined (I got 217.8 J/degreesC) and assuiming NaOH is the limiting reagent, what is delta H(neutralization) in kJ/mol?
dry-cleaning solvent (molecular weight = 146.99 g/mol) that contains C, H, and Cl is suspected to be a cancer-causing agent. When a 0.133 g sample was studied by combustion analysis, 0.239 g of CO2 and 0.0323 g of H2O formed. How many moles of eac..
