Urine on average has 4000 ng ACE/ ml. Therefore to convert these measurements of ng ACE / L pool water to ml urine / L pool water we need to divide each by 4000. Make a new vector showing the concentration of urine per liter in these 23 pools. What is the mean concentration of urine per liter

h let me think

it's filtration, but this is an assumption so my apologies if i got this

what is the average time it took the car to travel 0.25 meters?

⇒ 2.23 seconds

what is the average time it took the car to travel 0.50 meters?

⇒ 3.13 seconds

the dissociation of nickel hydroxide is follows:

the concentration of hydroxide ion is

the equilibrium constant value of nickel hydroxide is = 6.1 * 10^-^1^6 and thus equilibrium equation can be written as:

thus, concentration of ni is 0.23 * 10^-^4 mol /l
