Answer:
8.59 g
2.25 g
Explanation:
According to the given situation the calculation of grams of PbO and grams of NaCL is shown below:-
Moles of Pb(OH)CL is


= 0.0385 mol
Mass of PbO needed is

After solving the above equation we will get
= 8.59 g
Mass of NaCL needed is

After solving the above equation we will get
= 2.25 g
Therefore we have applied the above formula.
Answer:
<h2>12</h2>
Explanation:
The pH of a solution can be found by using the formula
