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
