27 + (35,5 + 2* 16) * 3 = 229.5 g/mol
<h3><u>Answer;</u></h3>
C. 352.6 m/s
<h3><u>Explanation;</u></h3>
Velocity of sound is dependent on temperature. An increase in temperature, increases the velocity of sound.
To calculate the velocity of the sound wave, we use this formula:
V = 331 + [0.6*T]; Where V is the velocity and T represents temperature.
When the temperature is 36 degree Celsius, we have
V = 331 + [0.6 * 36]
V = 331 + 21.6 = 352.6
Therefore,
V = 352.6 m/s.
