The empirical formula of a chemical substance is ch2. the molar mass of a molecule of the substance is 56.108 g/mol. what is the molecular formula of the chemical substance? a: c2h4 b: c4h8 c: c3h4 d: c6h6

- Molecular formula of the compound is .

Solution:- A molecular formula has n number of empirical formula units, where n is a whole number integer like 1,2,3 and so on.

Molar mass = n(empirical formula mass)

Empirical formula mass = 12.01+2(1.01)

= 12.01+2.02

= 14.03

Molar mass is given as 56.108. Let's plug in the values and calculate the value of n:

56.108 = n(14.03)

n = 4

Value of n is 4 means there are four empirical formula units involved to make the molecular formula of the compound.

So, the molecular formula of the compound is .

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.  

the earth would become to overheated and everything alive on it will eventually die from overheating. plants will eventually die as well, water will evaporate, and it will be nothing but a hot planet without anything living on it.
