Answer: when concentrations of acid and base are same, pH = pKa
PH = 12.38 pOH = 1.62
Explanation: pKa= -log(Ka)= 12.38. PH + pOH = 14.00
The group of atoms held together by covalent bonds is called a molecule
Answer:
<h2>18 g/mL</h2>
Explanation:
The density of a substance can be found by using the formula

volume = final volume of water - initial volume of water
volume = 62 - 52 = 10 mL
From the question we have

We have the final answer as
<h3>18 g/mL</h3>
