The empirical formula should be first determined. Empirical formula is the simplest ratio of whole numbers of components in a compound.
for 100 g of the compound
C H Cl
mass 46.47 g 7.80 g 45.72 g
number of moles 46.47 g/12 g/mol 7.80 g/1 g/mol 45.72 g/35.5 g/mol
= 3.87 mol = 7.80 mol = 1.29 mol
divide all by the least number of moles
3.87/1.29 = 3 7.80/1.29 = 6.04 1.29/1.29 = 1
when they are all rounded off to the nearest whole number
number of atoms are as follows
C - 3
H - 6
Cl - 1
the empirical formula is C₃H₆Cl
molecular formula is the actual number of components in the compound
molar mass = 155.06 g/mol
we have to find the mass of the empirical unit
mass of C₃H₆Cl - (12 g/mol x 3) + (1 g/mol x 6) + (35.5 g/mol x 1) = 77.5
we have to then find how many empirical units are in the molecular formula
number of units = molecular mass / empirical unit mass
= 155.06 g/mol / 77.5 = 2.00
there are 2 empirical units
molecular formula = 2 (C₃H₆Cl)
molecular formula - C₆H₁₂Cl₂

Answer:
450 g/mol
Explanation:
To solve the problem the problem, it is necessary to use Graham's Law of effusion
This answer is consistent with what we know. A heavier gas will require more time to effuse than a lighter gas
What will happen in a case there is different number of electrons compare to protons is<em> D: The particle is considered an</em><em> ion.</em>
<em></em>
- An ion can be regarded as atom or molecule which posses some amount of electron more than amount of protons and vice versa.
- It can be regarded as molecules that has a charge. i.e ( -ve or +ve)
- When the number of electron in this molecules or atom is more that that of the present protons, then the ion is negatively charged ion.
- When a particles posses less electron compare to the present protons then the ion is positively charged.
Therefore, an ion can be charged positively and it can be charged negatively
