The molecular formula gives us the total number of atoms of the compound. To do this we are going to count each of the atoms.
We have:
C = 4
H = 8
O = 2
So, the molecular formula will be C4H8O2
The empirical formula is the simplest way to represent a molecule, we simplify taking the denominators of the molecule to its simplest form, as they are all multiplies of two we can divide everything by this number and thus we obtain the empirical formula.
So, the empirical formula will be C2H4O
Answer:
<em>H.vap = 6.544 kJ/mol</em>
Explanation:
Clausius-Clapeyron Equation
<em>In P = H.vap / RT</em> where T = 20 + 273 = 293K
H.vap = In P (RT) = In 11 (8.314 x 293) = 6543.861 J/mol = 6.544 kJ/mol

The correct option would be 'electrons'
This is because electrons have a relative mass of zero.

Answer:
Depends on different states.
Explanation:
The wavelength of the photon that is emitted from the atom during the transition depends on the transition from different states. If the photon is emitted from n=4 state to n=3 state, the wavelength of photon is 1875 while on the other hand, if the photon is emitted from n=5 state to n=3 state, the wavelength of photon is 1282. If the photon is emitted from n=3 state to n=2 state, the wavelength of photon is 656.
