Since X is 1 g, therefore O must be 0.1 g. Therefore:
moles O = 0.1 g / (16 g / mol) = 0.00625 mol
We can see that for every 3 moles of O, there are 2 moles
of X, therefore:
moles X = 0.00625 mol O (3 moles X / 2 moles O) =
0.009375 mol
Molar mass X = 1 g / 0.009375 mol
<span>Molar mass X = 106.67 g/mol</span>
Answer:
50 MHz
Explanation:
The relation between frequency and wavelength is shown below as:
c is the speed of light having value 
Given, Wavelength = 6 m
Thus, Frequency is:
Also,
Also, 1 Hz = 
MHz
So,<u> Frequency = 50 MHz.</u>
