Answer:
3.75 * 10^7 g of this water would have been consumed.
Explanation:
ppm represents parts per million.
ppm = (mass solute / mass solution ) *10^6
⇒It is a way to express the concentration of very dilute solutions.
For this situation we have:
ppm = (grams of mercury / grams of solution ) * 10^6
0.004 = (x grams of mercury / 1g of solution) 10^6
x = 0.004 /10^6
x = 4 *10^-9 g Mercury
This mass of mercury is per gram of solution. In the next step, we can calculate the amount of solution (water plus mercury) that would have to be ingested to ingest 0.150 g of mercury
0.150 g of Hg * (1g of solution/ 4 *10^-9 g Mercury)= 3.75 *10^7
3.75 * 10^7 g of this water would have been consumed.
<span>They are all units of volume as are, Cubic Metres, Cubic Inches and Cubic Feet.
1mL and 1 cubic centimetre (cc) are the same.
Any one of the above is used to indicate the Density of substances which are compared to the density of pure water. By multiplying the Density of water by the Specific Gravity of the substance (Liquid or Solid), its density and, by calculation, it mass can be found. (cc and cmÂł are used for the solid materials. (a mL or Litre of copper or other solid doesn't quite sound right as they are used for liquid volume.</span>
Answer:
change of color
Explanation:
when a substance undergoes a change of color it is an indication that it was chemical
A good business atmosphere is an environment where everything is calm, maintaining, and positive. There also has to be good communication because, communication is key to a stress free atmosphere. everyone should work well and efficiently together. That is a good business atmosphere.
