Molarity : It is defined as the number of moles of solute present in one liter of solution.
Therefore, the molarity of solution is 3.33
Answer:
Osmium, 22.6 g/cc.
Iridium, 22.4 g/cc.
Platinum, 21.45 g/cc.
Rhenium, 21.2 g/cc.
Uranium, 20.2 g/cc.
these are are metals having a high density
Explanation:
The hydronium ion concentration when pH = 7 is : 8.75 * 10⁻⁹ mole/liter
<h3>Determine hydronium ion concentration when pH = 7 </h3>
Given that :
pH = 8.0
Hydronium ion concentration = 1 * 10⁻⁸ mole/liter
Resolving the question
8.0 = 1 * 10⁻⁸ mole/liter
7.0 = x
therefore :
x = 7 ( 1 * 10⁻⁸ ) / 8.0
= 8.75 * 10⁻⁹ mole/liter
Hence we can conclude that The hydronium ion concentration when pH = 7 is : 8.75 * 10⁻⁹ mole/liter
