Chemical Formula For An Unknown mineral?
An Unknow Mineral is in weight % 19.53 Si, 34.95 Mg, and 45.51 O.
What is the Atomic ratio of the elements, the chemical formula, and the name of this mineral??
Thanks a lot.
you have to convert to mole or atom fraction using the atomic weight of each of the elements (divide each of the percents by the atomic mass of the element). Then normalize (divide all of the atom percents by the lowest atom percent, making the least common element equal to 1 and the other elements some multiples of that element).
