<u>Answer:</u> The volume of stock solution of strontium hydroxide needed is 4.125 mL
<u>Explanation:</u>
1 mole of produces 1 mole of strontium ions and 2 moles of hydroxide ions
Molarity of diluted strontium hydroxide solution =
To calculate the molarity of the diluted solution, we use the equation:
where,
are the molarity and volume of the concentrated strontium hydroxide solution
are the molarity and volume of diluted strontium hydroxide solution
We are given:
Putting values in above equation, we get:
Hence, the volume of stock solution of strontium hydroxide needed is 4.125 mL
Since 1.00 atm is equal to 760 mmHg, the height of the column of mercury which would create pressure equal to 1.00 atm is 760 mm or 76 cm
<h3>What are the units of pressure?</h3>
Pressure is defined as the force acting perpendicularly per unit area of a surface.
The units of pressure include;
- millimetres of mercury, mmHg
- aatmospheres, atm,
- pascals, Pa
- Newtons per square metre, N/m^2
1 atmosphere is equal to 760 mmHg.
Therefore, the height of the column of mercury which would create pressure equal to 1.00 atm is 760 mm or 76 cm

The polar covalent bonding occurs when two atoms with different electronegativity form a covalent bond. This type of connection, the electrons are not equally shared. Typically, the atom having higher electronegativity attracts the electrons in the next link to it, thus forming a negative pole in its vicinity, and a positive pole of the next region less electronegative atom.
example: In the molecule HCl, hydrochloric acid, chlorine atom is more electronegative attracting electrons proximity to the bond with the hydrogen atom that is less electronegative, or more electropositive also rated.
hope this helps!.
I think it's N and O because on the left 3 times 2 gives you O6 on the left but O3 on the right. Then on the right 1×2= N2 but on the right it's just N1
0.69moles
Explanation:
Given parameters:
Number of atoms = 4.14 x 10²³atoms
Atom = Na
Unknown:
Number of moles of Na atom in it = ?
Solution:
A mole of a substance is the quantity of substance that contains the avogadro's number of particles.
1 mole = 6.02 x 10²³particles
To solve this problem, simply use the expression below;
Number of moles =
Input the parameters;
Number of moles = = 0.69moles
