Define the concentration measurements of parts per million

Chemistry
1 answer:
enyata [817]2 years ago
4 0

Answer:

Explanation:

Parts per million (ppm) is the number of units of mass of a contaminant per million units of total mass

ppm (or ppmm) is used to measure the concentration of a contaminant in soils and sediments. In that case 1 ppm equals 1 mg of substance per kg of solid (mg/kg).

Element M has two isotopes,^104M and ^106M.
snow_lady [41]
To calculate atomic mass, you have to take to weighted average of the isotopes' masses. What that means is M = RA*106 + (1 – RA)*104, where RA is relative abundance expressed in decimal form. If you simplify the right side of that equation, you get M = 2*RA + 104. Doing a little more algebra yields RA = (M –104)/2 = (104.4 – 104)/2 = 0.4 / 2 = 0.2, which is 20%. So the answer is B.
