- Table sugar (C12H22O11) or urea [(NH2)2CO] can be used by road crews to melt ice on roads, but solutions of CaCl2 are generally used instead. Assuming equal costs per pound of substance, why is CaCl2 used instead of table sugar or urea?arrow_forwardSpecifications for lactated Ringers solution, which is used for intravenous (IV) injections, are as follows to reach 100. mL of solution: 285315 mg Na+ 14.117.3 mg K+ 4.9Q.O mg Ca2+ 368408 mg Cl 231261 mg lactate, C3H5O3 a. Specify the amount of NaCl, KCl, CaCl2 2H2O, and NaC3H5O3 needed to prepare 100. mL lactated Ringers solution. b. What is the range of the osmotic pressure of the solution at 37C, given the preceding specifications?arrow_forwardCalculate the percent by mass of solute in each of the following solutions. 5.00 g of calcium chloride dissolved in 95.0 g of water 1.00 g of calcium chloride dissolved in 19.0 g of water 15.0 g of calcium chloride dissolved in 285 g of water 2.00 mg of calcium chloride dissolved in 0.0380 g of waterarrow_forward
