You just have to convert the mass of water into volume.
To do that you use the density of water, which is about 1.0 g/ ml
So, from the formula of density D = M / V, you get V = M / D
=> V = 2.49 * 10^7 grams / 1.0 g / ml = 2.49 * 10 ^ 7 ml
You can pass that to liters using the conversion factor 1000 ml = 1 l
2.49 * 10^7 ml * 1 l / 1000 ml = 2.49 * 10^4 l = 24,900 l
Answer: 24,900 l
Answer:
The answer to your question is pH = 9.08
Explanation:
Data
pH = ?
Concentration = 1.2 x 10⁻⁵ M
Process
1.- Calculate the pOH of the solution
Formula
pOH = -log[OH⁻]
pOH = -log[1.2 x 10⁻⁵]
pOH = 4.92
2.- Calculate the pH
Formula
pH = 14 - pOH
Substitution
pH = 14 - 4.92
Result
pH = 9.08
