7 0
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...

vekshin1

Answer:

<em>The three gases, in the three identical containers, will all have the same number of molecules</em>

Explanation:

If these three gases (Helium He, Neon Ne, and Oxygen O_{2}) are all contained in separate identical containers with the same volume. And they are all stored at the same temperature, and pressure. Then, they'll all contain the same number of molecules. This is in line with Avogadro's law which states that "Equal volume of all gases, at the same temperature and pressure, have the same number of molecules."

What is the [H+] concentration of blood, given the ph is 2.5?
belka [17]

Answer:

0.00316

Explanation:

You have to use the following equation:

pH=-log[H^+]

You are given the pH and need to find the concentration of H+.  Plug in the given components and solve.

2.5=-log[H^+]\\H^+ = 10^{-2.5}\\H^+=0.00316

The concentration of H is 0.00316.
