Answer:
what does the photo look like
Explanation:
Answer:
The new pH of the solution 
Explanation:
Given
pH of bottle of Soda is 
As we know that
pH 
log [H+]
We will derive the hydrogen ion concentration when pH is
log [H+]
Taking anti-log on both the sides, we get -
H+ ion is equal to 
When the hydronuim ion concentration reduces by 
of the original concentration, the new hydrogen ion concentration becomes
The new pH is
![= - log [ 10^{-6}]\\= 6](https://tex.z-dn.net/?f=%3D%20-%20log%20%5B%2010%5E%7B-6%7D%5D%5C%5C%3D%206)

the point at which a liquid turns to gass
<h3>
Answer:</h3>
318.405 g
<h3>
Explanation:</h3>
We are given;
- Volume of K₃PO₄ solution to be prepared as 750.0 mL or 0.75 L
- Molarity of the solution to be prepared as 2.00 M
We are required to determine the mass of K₃PO₄ to be measured.
<h3>Step 1: Determine the number of moles of K₃PO₄</h3>
Molarity = Moles ÷ Volume
Rearranging the formula;
Number of moles = Molarity × Volume
Therefore;
Moles of K₃PO₄ = 2.00 M × 0.75 L
= 1.5 moles
<h3>Step 2: Determine the mass of K₃PO₄ to be measured</h3>
Mass = Number of moles × Molar mass
Molar mass of K₃PO₄ = 212.27 g/mol
Therefore;
Mass of K₃PO₄ = 1.5 moles × 212.27 g/mol
= 318.405 g
Therefore, the mass of K₃PO₄ that should be weighed is 318.405 g
