Answer:
Molarity=0.0058M
Explanation:
Given the weight of AgN
is(w) 1.24g
We know that the molecular weight of AgN
is(W) 169.87g/mol.
Given the volume of the solution is(V) 125ml.
Here solute is silver nitrate and the solvent is water.
We know that
![Molarity=\frac{number of moles of solute}{total volume of the solution int litres}](https://tex.z-dn.net/?f=Molarity%3D%5Cfrac%7Bnumber%20of%20moles%20of%20solute%7D%7Btotal%20volume%20of%20the%20solution%20int%20litres%7D)
We know that number of moles=weight/molecular weight
= ![7.3*10^{-3}](https://tex.z-dn.net/?f=7.3%2A10%5E%7B-3%7D)
volume of the solution(V)=125/1000=0.125L
Now
Molarity=n/V
M=
=0.00584M
To convert the expanded form into exponent form or what is commonly known as scientific notation, you have to move the decimal place until you reach the last digit. From its original place, there are 6 places in order to reach to the last digit. Since you moved to the right, the exponent would have a positive sign. The scientific notation would be 6×10⁶ m.
Answer: Groundwater that forms caves because it is slightly acidic.
Explanation:
The water under the ground present inside the cracks and spaces in sand, soil and rocks is called ground water.
When ground water moves through the soil it results in the formation of acid. Further, this acid helps minerals to get dissolve. These minerals get deposited on other places as well.
This process of deposition and erosion helps in the formation of caves.
Thus, it can be concluded that groundwater that forms caves because it is slightly acidic.
