Given :
Concentration of hydrogen ions,
.
To Find :
The pH of a solution.
Solution :
We know, pH of a solution is given by :
![pH = - log [ H^+]\\\\pH = -log ( 10^{-3})\\\\pH = 3](https://tex.z-dn.net/?f=pH%20%3D%20-%20log%20%5B%20H%5E%2B%5D%5C%5C%5C%5CpH%20%3D%20-log%20%28%2010%5E%7B-3%7D%29%5C%5C%5C%5CpH%20%3D%203)
Therefore, the pH of the solution is 3 .
Accuracy is how close a value is to its true value. An example is how close an arrow gets to the bull's-eye center. Precision is how repeatable a measurement is. An example is how close a second arrow is to the first one (regardless of whether either is near the mark).

Answer is: <span>he boiling point of a 1.5 m aqueous solution of fructose is </span>100.7725°C.
The boiling point
elevation is directly proportional to the molality of the solution
according to the equation: ΔTb = Kb · b.<span>
ΔTb - the boiling point
elevation.
Kb - the ebullioscopic
constant. of water.
b - molality of the solution.
Kb = 0.515</span>°C/m.
b = 1.5 m.
ΔTb = 0.515°C/m · 1.5 m.
ΔTb = 0.7725°C.
Tb(solution) = Tb(water) + ΔTb.
Tb(solution) = 100°C + 0.7725°C = 100.7725°C.
