If you had been asked to identify the metal you would have needed the formula (or would have needed to test the likely formulas to see if they produced reasonable results.) Given an equivalent weight for M of 12g: M X 2 O 12 g / m o l, c a r b o n (not a metal) M O 24 g / m o l, m a g n e s i u m

WebPlease refer to the answer of Mr. Ramesh. If the metal X is considered and the weight of the metal is M gm then the equivalent weight of the metal X would be M/2 as the definition of equivalent weight suggests that the weight of the metal that combines with 8 parts of Oxygen is the equivalent weight of that substance. Web(N.B., Dividing a gram into a million equal parts results in a million micrograms, i.e., a ug is a millionth of a g; similarly a millionth of a kg is a mg, hence, by weight, a ppm = ug/g =... how did beech island sc get its name

WebActinium is a chemical element with the symbol Ac and atomic number 89. It was first isolated by Friedrich Oskar Giesel in 1902, who gave it the name emanium; the element got its name by being wrongly identified with a substance André-Louis Debierne found in 1899 and called actinium. Actinium gave the name to the actinide series, a set of 15 ...
