where w is the grams of Mg used and z is the grams of O incorporated. The empirical formula of magnesium oxide, Mg x O y, is written as the lowest whole-number ratio between the moles of Mg used and moles of O consumed.This is found by determining the moles of Mg and O in the product; divide each value by the smaller number; and, multiply the resulting values by small whole numbers (up to five.

Just the other day I came across this formula. the element-wise distance of the rank vectors multiplied by 6/(n*(n²-1)). As it is defined, d² takes a minimum value of 0 when the rank vectors.

In nuclear physics, the semi-empirical mass formula (SEMF) (sometimes also called Weizsäcker’s formula, or the Bethe–Weizsäcker formula, or the Bethe–Weizsäcker mass formula to distinguish it from the Bethe–Weizsäcker process) is used to approximate the mass and various other properties of an atomic nucleus from its number of protons and neutrons.
