Answer:
5 ounces of solution are left in the bottle.
Step-by-step explanation:
Volume of the staining solution, s = 30 oz
Volume required for the blood staining test = [tex]\frac{3}{4}[/tex] of solution
[tex]=\frac{3}{4}\times 30 = 22.5 oz[/tex]
Volume required for blood tests = [tex]\frac{1}{2}oz=0.5 oz[/tex]
Number of blood staining tests run = 1
Volume of solution required in 1 blood staining test ,x= 22.5 oz × 1 = 22.5 oz
Number of blood test run = 5
Volume of solution required in 5 blood test ,y= 0.5 oz × 5 = 2.5 oz
Volume of staining solution left : s - x- y
= 30 oz - 22.5 oz - 2.5 oz = 5 oz
5 ounces of solution are left in the bottle.
