(Raleigh NC USA)
An order for 6 liters of 0.9% soium chloride solution is to be prepared from 23.4% concentrated NaCl solution and sterile water for injection.How many mL of each will be used?
The answer is supposed to be 231 mL of 23.4% and 5769 mL of water but I can't seem to figure out how they got their answer or what formula they used. What is the tic tac toe board supposed to look like? Do I multiply by 6, 6000, or 1000? or do i do the usual cross multiply and divide with the 1000?
