Finding percentage of hydrogen

WebJan 24, 2024 · To find the mass percent composition of an element, divide the mass contribution of the element by the total molecular mass. This number must then be multiplied by 100% to be expressed as a percent. For K: Mass percent composition of K = mass contribution of K/molecular mass of K 3 Fe (CN) 6 x 100%. WebDec 28, 2024 · It gives the percentage of mass contributed by one particular element in the compound. The formula to calculate the percent composition of any given compound is. %CE = (gE/gT) x 100. Where, %CE is the percentage composition of the element to be calculated, gE is grams of the element, and. gT is the total mass of the compound in grams.
