Question

Suppose you dissolve 7 g of AlCl3, 2 g of CaCI2, and 10 g of NaBr in 1 L of water Express the concentrations of Na+, Ca+2, Ar3 , and Cl in mM and mEq/L. Calculate the osmolality and osmolality of the solution at 37 C. You will need to look up the density of water at this temperature C A commonly-used intravenous fluid in surgical and intensive care is D5 Lactated Ringer's (LR) solution. Look up the concentrations of Na+. K+. Cl-, lactate, dextrose, and Ca++ in LR (in mEq/L) and use these values to calculate the osmolarity of LR Then look up and report a standard range of normal plasma osmolarities. Is LR hypoosmotic isoosmotic. or hyperosmotic relative to plasma? For any values you look up for this and subsequent problem sets, cite your source, e g . a specific web page or textbook
