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

when you strongly heat the potassium chlorate it leaves oxygen if you'll not heat it strongly to decompose it the oxygen would not release and the compound will remain thermally unstable.
The answer would be 25% of an atom
<span>Missing question: sulfanilamide has a solubility in 95% ethanol of </span>210 mg/ml<span> at 78 degree Celsius.
m(</span>sulfanilamide) = 0,75 g = 0,75 · 1000 = 750 mg.
210 mg : 1 ml = 750 mg : V(ethyl alcohol).
210 mg · V(ethyl alcohol) = 750 ml · mg.
V(ethyl alcohol) = 3,57 ml.
Answer is: 3,57 ml <span>of 95% ethyl alcohol will be required.</span>
