Hello!
The concentration of hydronium ions is related to pH by the following simple equation:
![pH=-log[H_3O^{+}]](https://tex.z-dn.net/?f=pH%3D-log%5BH_3O%5E%7B%2B%7D%5D%20)
From this equation, you can see that as the hydronium concentration is higher, the pH will be lower.
The concentration of the OH⁻ ions is related to the pH by the following set of equations
![pOH=-log[OH^{-}] \\ pH=14-pOH](https://tex.z-dn.net/?f=pOH%3D-log%5BOH%5E%7B-%7D%5D%20%5C%5C%20pH%3D14-pOH)
You can see that as the concentration of OH⁻ is higher, the pOH is lower and thus the pH is higher.
When the pH of the solution is less than 7, the solution is acidic.
When the pH of the solution is higher than 7, the solution is basic.
Have a nice day!

Answer:
Mass on the moon is 5.1 kg.
Explanation:
Given mass on earth = 5.1 kg
acceleration due to gravity on moon = 1.6 ms⁻².
The mass on the moon does not change because mass is the quantity of matter in the body regardless of its volume or of any forces acting on it.
Whereas the weight of the object changed.
Weight is the the force exerted on a body which is related to mass and expressed as W = mg.
W = weight of object m = mass of object and g = gravitational force
N stands for newton unit of weight.
Thus mass of the object on moon is same as on earth which is 5.1 kg.
