This question is a dilution problem. In order to prepare a certain concentration and volume from a stock solution, you have to use the equation,
M1V1 = M2V2
From the equation, you need to calculate the volume you need from the stock solution to be able to have the diluted concentration then dilute it to a certain volume.
(1.0 M) (V1) = (0.1 M) (100 mL)
V1 = 0.1 mL is needed from the 1.0 M HCl solution
First you should know that there is seven oxygen atoms in one Mn2O7
So
2.00 moles of Mn2O7 contain 14.00 moles of oxygen...
Then you multiply this no. with Avagadro no....
from formula
Number of moles= no. of particles/avagadro's no..
14.00×6.02×10²³=84.28 atoms of oxygen...
Answer:
Sea floor spreading occurs in mid-ocean ridges
Explanation:
mid-ocean ridge: A location where sea floor spreading occurs. The release of magma at these active volcanic sites forms new rocks and rows of mountains.
The solutions vapor pressure would be lower.
