What is the empirical formula of a substance that consists of 85.60% carbon and 14.40% hydrogen?

assuming you have 100 grams of sample

85.60gC/molecular weight 12g = 7.13

14.40gH/molecular weight 1.008g = 14.2857

divide the larger amount calculated by the smaller 14.2857/7.13 = 2

so 7.13 means oneC and 14.2857 means twoH

CH2 ethylene

in chemistry, a solution’s concentration is how much of a dissolvable substance, known as a solute, is mixed with another substance, called the solvent. the standard formula is c = m/v, where c is the concentration, m is the mass of the solute dissolved, and v is the total volume
