The molecular formula is a chemical formula which indicates the exact number of atoms present in the molecule.
The given molecular formula is and the name of this molecule is propane consist of three carbon atoms which are linked with eight hydrogen atoms by single bonds.
Now, the figure 1 shows the condensed structural formula, figure 2 shows the structural formula and figure 3 shows the skeletal structural formula of propane.
When you combine protons and neutrons in the electrical charge they combine to make electricity

Answer:
frequency = 2.07 x 10¹³ Hz
Explanation:
To find the frequency of the photon, you need to use the following equation:
E = hv
In this formula,
-----> E = energy (J)
-----> h = Planck's Constant (6.626 x 10⁻³⁴ J*s)
-----> v = frequency (Hz)
Since you have been given values for two of the variables (in the correct units), you can plug them into the equation and simplify to find the frequency.
E = hv <----- General Equation
E = (6.626 x 10⁻³⁴ J*s)v <---- Plug in Planck's Constant
1.37 x 10⁻²⁰ J = (6.626 x 10⁻³⁴ J*s)v <----- Plug in energy (given)
2.07 x 10¹³ = v <----- Divide both sides by 6.626 x 10⁻³⁴
