relative atomic mass, percentage comp. Flashcards
what is relative atomic mass?
average mass of all stable isotopes
how is relative atomic mass calculated?
from the percentage composition
formula for relative atomic mass (Ar)
Ar = (percent x isotopic number) + (percent x isotopic number) divided by 100
how to calculate percentage comp.
(component mass / total mass) x 100
how to calculate percentage comp. of elements in a compound
element mass = (element % x mass of compound) divided by 100
examples ofgravimetric analysis in industry
mining industry for mineral ores this is important because:
It provides accurate quantification, which are precise and accurate measurements of specific elements or compounds within a mineral ore, which determines the ore’s value and usability.
Gravimetric analysis is also a tool used in the nutrition and food industry for these reasons:
It provides accurate and precise measurements of essential nutrients such as proteins, fats, carbohydrates, vitamins, and minerals.
