A pharmacist has 80 milileters of a 25 percent saline solution. Which expression can be used to find the percentage of the conce
Thepotemich [5.8K]

Answer:


Step-by-step explanation:

Final concentration % = [grams of salt / mililiters of solution] * 100


grams of salt = grams of salt from solution 1 + grams of salt from solution 2


grams of salt from solution 1 = mililiters * %/100 = 80 mililiters * 0.25 g/mililiters = 20 g


grams of salt from solution 2 = mililiters *%/100 = x*0.10 g/mililiters = 0.1x


mililiters of final solution = mililiters from solution 1 + mililiters from solution 2


mililiters of final solution = 80 mililiters + x mililiters


=> Final concentration, %  =  [0,10x + 20 g] / [x + 80 mililiters] * 100
