Answer:
1. 40 grams of NaCI
2. 20 grams of Barium Peroxide
Explanation:
<h3><u>
In this question, we have to divide to find the amount of each element in a drop. </u></h3>
For Question 1, there are 400 grams of NaCI. There are 10 drops.
So, we have to divide 400 by 10.
We get 40 as our result, so 40 is the answer.
<h3><u>
Same for this question, we use the process we did before.</u></h3>
There are 800 grams of barium peroxide, and there are 40 drops.
So, we divide 800 by 40.
We have the answer as 20.
Our final answers are going to be listed below:
- Question 1 - 40
- Question 2 - 20
Hope this helps you!

Answer:
pH is calculated by taking negative logarithm of hydrogen ion concentration. Acids have pH ranging from 1 to 6.9, bases have pH ranging from 7.1 to 14 and neutral solutions have pH equal to 7. Thus the sum of pH and pOH is 14
