<u>Answer:</u> The density of NaCl solution is 3.930 g/mL
<u>Explanation:</u>
We are given:
Mass of cylinder,
= 21.577 g
Mass of NaCl and cylinder combined, M = 39.664 g
Mass of NaCl,
= 
To calculate density of a substance, we use the equation:

We are given:
Mass of NaCl = 18.087 g
Volume of NaCl solution = 4.602 mL
Putting values in above equation, we get:

Hence, the density of NaCl solution is 3.930 g/mL

Answer:
3. Which side of the chain should you count from when naming organic compounds?
C) Side that will give you the longest Carbon chain
4. What is the pH of a solution with a pOH of 10?
C) 4
pH + pOH = 14
pH + 10 = 14
pH = 14 - 10
pH = 4
