Can someone please help me come up with an empirical and molecular formula for these abundances? Based on the mass spectrum the molecular mass of the molecule is 94. C63H142Br7 seems absurd and so does C27H61Br3. I don't know if the spectrum is wrong, or if I can't do math but I need a second opinion, please. C= 51.89% H= 9.82% Br=38.29%

each chemical family is represented as a group or column on the periodic table. based on chemical properties, there are 6 types of chemical families. group 1 represents alkali metals, group 2 represents alkaline earth metals, groups 3 to 12 represent transition metals, groups 13 to 16 represent non-metals and other metals, group 17 represents halogens and group 18 represents noble gases.

idk what is it? is this a question that you know the answer or u dont
