No I do not agree with that at all. check on a calculator
The pH is the measure of hydrogen ion concentration in a solution. The hydrogen ion concentration at pH 1.25 is
.
<h3>How to calculate hydrogen concentration?</h3>
The pH is the negative logarithmic value of the hydrogen ion concentration in the sample.
The pH can be expressed as:
![\rm pH=-Log[H^+]](https://tex.z-dn.net/?f=%5Crm%20pH%3D-Log%5BH%5E%2B%5D)
The hydrogen ion concentration can be given as:
![\rm [H^+]=10^{-pH}](https://tex.z-dn.net/?f=%5Crm%20%5BH%5E%2B%5D%3D10%5E%7B-pH%7D)
The given pH is 1.25 The hydrogen ion concentration is given as:
![H^+=10^{-1.25}\\H^+=0.05\ M\\h^+=5\times10^{-2}\ m](https://tex.z-dn.net/?f=H%5E%2B%3D10%5E%7B-1.25%7D%5C%5CH%5E%2B%3D0.05%5C%20M%5C%5Ch%5E%2B%3D5%5Ctimes10%5E%7B-2%7D%5C%20m)
The hydrogen ion concentration in the solution is .![5\times 10^{-2}\ M](https://tex.z-dn.net/?f=5%5Ctimes%2010%5E%7B-2%7D%5C%20M)

Answer:
x(x+8) = 256
Step-by-step explanation:
hello
one side is x
the other one is 8 yards longer, so it is x + 8
so the surface is x(x+8) = 256
hope this helps
Answer: Meera is 24
Step-by-step explanation:
suppose the present age of meera is x years
by the given condition
1/2(x+2)+1/3(x-3)=20
3(x+2)+2(x-3)=120 ..............multiply by 6
3x+6+2x-6=120
5x=120
x=24
hence the present age of meera is 24 years.
