Answer: In sound waves, energy is transferred through vibration of air particles or particles of a solid through which the sound travels
Explanation: In electromagnetic waves, energy is transferred through vibrations of electric and magnetic fields. In water waves, energy is transferred through the vibration of the water particles.
<u>Answer:</u> The molarity of the stock solution is 4.64 M
<u>Explanation:</u>
To calculate the molarity of the diluted solution, we use the equation:
where,
are the molarity and volume of the stock solution
are the molarity and volume of diluted solution
We are given:
Putting values in above equation, we get:

Hence, the molarity of the stock solution is 4.64 M
None of the above the answer would be D
M (NaCl) = n × M = 3.75 × 58.5 =
219.375 g
M (NaCl) = 23 + 35.5 = 58.5 g/mol
