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

Step-by-step explanation:

many things are possible.

the only thing we must not do is mixing the addition elements with the multiplication elements.

but we could change the expression to

3×(3×8) + 5

5 + (3×3)×8

5 + (3×8)×3

and so on, and it would always be the same result.
