Answer:
The molarity of the solution is 1.1 
Explanation:
Molarity is a measure of the concentration of that substance that is defined as the number of moles of solute divided by the volume of the solution.
The molarity of a solution is calculated by dividing the moles of the solute by the volume of the solution:

Molarity is expressed in units 
In this case
- number of moles of solute= 0.564 moles
- volume= 0.510 L
Replacing:

Solving:
molarity= 1.1 
<u><em>The molarity of the solution is 1.1 </em></u>

Answer:
Because we need to dispense 4.7 mL, the volume reading in the pipet is the 5.3 mL line.
Explanation:
First we use C₁V₁=C₂V₂ in order to <u>calculate the required volume of concentrated HCl</u> (V₁):
12.85 M * V₁ = 0.600 M * 100 mL
V₁ = 4.7 mL
<u>So we need to dispense 4.7 mL of the concentrated HCl solution</u>. The mark in the pipet that would contain that volume would be 10.0 - 4.7 = 5.3 mL

Na(sodium)=2.8.1
Cl (Chlorine)=2.8.7. sodium will give the chlorine the 1 valence electron to become stable ions.

Answer:
6.37.
Explanation:
What is given?
[H (+)] = 4.25 x 10⁻⁷ mol/dm³
Step-by-step solution:
First, let's see the formula to calculate the pH based on the hydrogen ion concentration (H (+)):
![pH=-log\lbrack H^+].](https://tex.z-dn.net/?f=pH%3D-log%5Clbrack%20H%5E%2B%5D.)
*Logarithm must be in base 10!
Our given concentration of hydrogen ion is 4.25 x 10⁻⁷ mol/dm³. Remember that the units of concentration must be in M (mol/L) but in this case, 1 dm³ equals 1 L, so based on this, we have that:

So, we can replace this value in the formula of pH:
![pH=-log\lbrack4.25\cdot10^{-7}]\approx6.37.](https://tex.z-dn.net/?f=pH%3D-log%5Clbrack4.25%5Ccdot10%5E%7B-7%7D%5D%5Capprox6.37.)
The pH of milk would be 6.37 which means that is slightly acid (weak acid).
