C. Diffusion is not a phase change.
Answer:
M = 3.69 M.
Explanation:
Hello there!
In this case, according to the given information, it turns out possible for us to calculate the molar concentration of the 1.29 moles of KCl in 350 mL of solution by recalling the mathematical definition of molarity as the division of the moles by the volume in liters, in this case 0.350 L; thus, we proceed as follows:

Which gives molar units, M, or just mol/L.
Regards!

Answer:
77%
Explanation:
First we <u>convert 3.0 g of cyclohexanol (C₆H₁₂O) to moles</u>, using its <em>molar mass</em>:
- Molar mass of C₆H₁₂O = 100.158 g/mol
- 3.0 g ÷ 100.158 g/mol = 0.030 mol
Then we <u>convert 1.9 g of cyclohexene (C₆H₁₀) to moles</u>, using its <em>molar mass</em>:
- Molar mass of C₆H₁₀ = 82.143 g/mol
- 1.9 g ÷ 82.143 g/mol = 0.023 mol
Finally we <u>calculate the theoretical yield</u>:
- 0.023 mol / 0.030 mol * 100% = 77%
