in the winter of 1994, record low temperatures were registered throughout the united states. for example, in champaign, illinois, a record low of -29°f was registered. at this temperature can salting icy roads with cacl2 be effective in melting the ice? (the solubility of cacl2 in cold water is 74.5 g per 100.0 g of water.)
(a) assume i = 3.00 for cacl2.
(b) assume i = 2.60

why does it work for 3.00 but not 2.60? i'm confused as to how i process this question and explain it.

Determine the number of moles of air present in 1.35 l at 750 torr and 17.0°c. which equation should you use? n=pv/rt what is the number of moles present? ⇒ 0.056 mol a sample of n2 gas occupying 800.0 ml at 20.0°c is chilled on ice to 0.00°c. if the pressure also drops from 1.50 atm to 1.20 atm, what is the final volume of the gas? which equation should you use? v2= p1v1t2/p2t1 what is the final volume of the gas? ⇒ 932 ml these are the answers
