- Why is mass fraction always abbreviated wt% and not ma%?
What bothers me is that "wt" refers to the weight, which is a force, not a mass I know it is common usage to use "weight" to refer to the mass of an object, but when writing science shouldn't we be more accurate and use the proper words? Molar and volume fractions are abbreviated mol% and vol%, respectively
- How do I convert an element measurement to oxides?
For what you want to do, going from wt% element to wt% oxide, all you have to do is multiply by a conversion factor, which is 2 1393 for silicon (the 0 4674 factor you mentioned is to go the other way around, from oxide to element)
- geology - How can I normalize this chemical analysis to a mineral with . . .
The molecular weight given of FeO F e O = 72, and the mw of TiOX2 T i O X 2 = 80 The first step I did was divide each wt% by their molecular weights to get a molecular proportion: FeO: 70 72 = 0 972 F e O: 70 72 = 0 972 TiOX2: 30 80 = 0 375 T i O X 2: 30 80 = 0 375 Then, I multiplied each proportion by the number of oxygens in each chemical
- Analyzing composition of a mineral using SEM
If I have a mineral in which I did a SEM analysis on and got the data (elements and their wt% with Std Dev , MDL, atomic % oxide % and k ratio) how would I go about quantifying the sample's compo
- What is a reasonable method of estimating the volume percent of a . . .
I would like to trim some data by making rough estimations of the possible volume percent muscovite in a sample given pXRF data which provides a wt% potassium Muscovite and K-feldspar are the only
