Determine the pH of a solution made by diluting 25mL of 6.0 M HCl until the final volume of the solution is 1.75 L
ValentinkaMS [17]
First calculate the Molarity <span>of the final solution :

C</span>₁ = 6.0 M

V₁ = 25 mL

C₂ = ?

V₂ = 1.75 * 1000 = 1750 mL

C₁ * V₁ = C₂ * V₂

6.0 * 25 = C₂ * 1750

150 = C₂ * 1750

C₂ = 150 / 1750

C₂ = 0.08571 M

Therefore:

pH = - log [C₂]

pH = - log [ <span>0.08571 ]
</span>
pH = 1.0669

hope this helps!

If 12 gallons of gasoline cost $34.68, what is the unit price per gallon?
chubhunter [2.5K]
The answer is $2.89.

Since it’s asking for the unit price of one gallon and you have the total ($34.68 and 12 gallons), you would divide $34.68 from 12, which gives you $2.89.

34.68/12 = 2.89
