The amount of the magnesium in the sample in ppm is 497 ppm.
<h3>What is parts per million?</h3>
The term parts per million refers to one of the manners in which concentration is expressed. It is common in oceanography and analytical chemistry.
Given that;
Mass of Mg= 0.0549 g
Mass of the sample = 110.52 g
Amount in PPM = 0.0549 g/110.52 g * 10^6
= 497 ppm
