Calculate the ph of a solution whose(oh^-) is 4.583*10^-5 mole dm cube (pkw=14)​
Sergeu [11.5K]

pH of solution = 9.661

<h3>Further explanation </h3>

pH is the degree of acidity of a solution that depends on the concentration of H⁺ ions. The greater the value the more acidic the solution and the smaller the pH.

pH = - log [H⁺]

So that the two quantities between pH and [H⁺] are inversely proportional because they are associated with negative values.

pOH=-log[OH⁻]

\tt pOH=-log[4.583\times 10^{-5}]\\\\pOH=5-log~4.583=4.339

pH+pOH=pKw

\tt pH=14-4.339\\\\pH=9.661

How many moles are 7 grams of calcium oxide? (Atomic mass of Calcium - 40 u, oxygen-16 u)​
White raven [17]

Answer:

0.125

Explanation:

no of moles = given mass / molar mass

no of moles = 7/

molar mass of calcium oxide = atomic mass of calcium + oxygen

molar mass = 40 + 16

molar mass = 56

no of moles = 7/ 56 = 1/8 = 0.125
