0,15 moles of NaOH-------in------------1000ml
x moles of NaOH------------in--------100ml
x = 0,015 moles of NaOH
final volume = 150ml
0,015 moles of NaOH---in-------150ml
x moles of NaOH--------------in-----1000ml
x = 0,1 moles of NaOH
answer: 0,1mol/dm³ (molarity)
It is important to make sure the solvent is level and not at an angle so you do not get an angled solvent front.
Answer : The correct option is, increase amplitude.
Explanation :
Amplitude : It is a measure of the size of sound waves.
The loudness of sound is depend on the amplitude of the sound wave. That means the more the amplitude, the louder will be the sound and the less the amplitude, the low will be the sound.
The loudness of sound does not depend on the tension and wavelength.
Therefore, the correct answer is, increase amplitude.
