A formula that shows the elements in a compound i their lowest whole number ratio
CO2 is the emperical formula of carbon dioxide
Answer:
0.2625L
Explanation:
Given parameters":
Volume of solution = 1.25L
Percentage concentration = 21%
Unknown:
Volume of methanol = ?
Solution:
The percentage concentration is one of the different methods for expressing concentration values.
It is given as:
Percentage concentration =
Now we have to work backwards to derive the percentage concentration;
let the unknown, the volume of methanol which is the solute = P;
21 = x 100
21 =
21 = 80p
p = 0.2625L
Explanation:
There are several ways to define acids and bases, but pH and pOH refer to hydrogen ion concentration and hydroxide ion concentration, respectively. The "p" in pH and pOH stands for "negative logarithm of" and is used to make it easier to work with extremely large or small values. pH and pOH are only meaningful when applied to aqueous (water-based) solutions. When water dissociates it yields a hydrogen ion and a hydroxide.
