Astream of humid air containing 2.50 mol% h2o(v) and the balance dry air is to be humidified to a water content of 10.0 mole% h20. for this purpose, liquid water is fed through a flowmeter and evaporated into the air stream. the flowmeter reading, r, is 105.0. the only available calibration data for the flowmeter are two points scribbled on a sheet of paper, indicating that readings r = 21.0 and r = 54.0 correspond to flow rates v = 42.0 ft/h and v = 100.9 ft/h, respectively. water flow estimate the flow rate of the liquid water feed if the volumetric flow rate is a linear function of r. v= / 1 lb-mole/h estimate the flow rate of the liquid water feed if the reading ris a linear function of v . v= ib-mole/h

What happens when the temperature of a solution increases?

Nconcentration refers to the molar concentration of an ion in solution. it may be identical to, or greater or less than, the molar concentration of the compound containing the ion that was used to make the solution. for soluble salts, the molarity of a particular ion is equal to the molarity of that compound times the subscript for that ion. for example, 1 m of alcl3 is 1 m in al3+ and 3 m in cl−. 1 m of (nh4)2so4 is 2 m in nh4+ and 1 m in so42−. part a what is the concentration of k+ in 0.15 m of k2s? view available hint(s) nothing m m part b if cacl2 is dissolved in water, what can be said about the concentration of the ca2+ ion? view available hint(s) if is dissolved in water, what can be said about the concentration of the ion? it has the same concentration as the cl− ion. its concentration is half that of the cl− ion. its concentration is twice that of the cl− ion. its concentration is one-third that of the cl− ion. part c a scientist wants to make a solution of tribasic sodium phosphate, na3po4, for a laboratory experiment. how many grams of na3po4 will be needed to produce 550 ml of a solution that has a concentration of na+ ions of 0.700 m ? express your answer numerically in grams. view available hint(s) mass of na3po4 n a 3 p o 4 = nothing g provide feedback
