Answer:
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value 
Given, Frequency = 103.4 MHz = 
( as 1 MHz = 10⁶ Hz)
Thus, Wavelength is:
<span>If you look up the density of Acetone (Propanone in IUPAC names) you will find it is 0.7925g/cm3. This is the same as 0.7925g/ml.
You can calculate mass using the equation:- mass = density x volume
In your example mass = 0.7925 x 28.40 = 22.51g</span><span>
I think That's right. Hope this helps!!! Good luck!</span>
Answer:
