Now if we combine hydrogen and chlorine according to the above ratio which is one hydrogen and one chlorine .
HCL
1:1
so it is a stable compound hydrogen chloride gas.
CH4 : CCL4
1/4 : 1/4
after this cross multiplication and 4 cut with 4 and the answer is
1:1 or or HCL 1:1
* ATOMIC MASS:-
Atomic mass of an element is the mass of atom of that element which is taken out by compairing with the mass of hydrogen atom which is 1.
OR
The mass of an atom of element which is taken out by compairing with 12th part of a carbon tweleve(12C) is called atomic mass.
The mass of an atom of an element which is taken out by compairing with 1/12th part of carbon .
Atoms of same elements having same atomic number (number of electrons) but different atomic mass ( number of proton and neutron).
some some elements have isotopes, so there atomic mass are taken as the average of atomic masses of their isotopes. The average of atomic masses of an element can be calculated from nature abundances of isotopes of that element.
Chlorine has two isotopes CL-35 and CL-37. The natural abundances of CL-35 is 75% and of CL-37 is 25% so the average atomic mass of CL can be calculated by following equation.
averege atomic mass of Chlorine=(75*35)+(25-37)
