The horizontal distance represents wavelength λ. The time represents the period of the wave T.
Wave speed is given by v= λ/T
Hence, those are the only parameters needed.
Note: the vertical distance is for calculating amplitude which is not used in calculating wave speed.
The term mole refers to 6.02x10²³ atoms or molecules of any substance. so regardless of the substance one mole will always be equivalent to 6.02x10²³
Hope that helps
The new volume of the bag will be 789.5 mL.
<u>Explanation:</u>
As per the Charles law, at constant pressure the volume of the gas is directly related to its temperature in Kelvin (K). That is as the temperature increases, the gas expands and vice-versa.

V1 = 250 ml
V2 = ?
T1 = 19° C
T2 = 60° C
Now we have to rewrite the equation to get the new volume as,
V2 = 
=
<em> </em>= 789.47 ≈ 789.5 ml.
So the new volume of the bag will be 789.5 mL.
Answer:
The answer is “3 moles of molecules”.
