In 1993 the minnesota department of health set a health risk limit for cadmium in groundwater of 4.00 μg. suppose an analytical chemist receives a sample of groundwater with a measured volume of 76.0 ml. calculate the maximum mass n micrograms cadmium which the chemist could measure in this sample and still certify that the groundwater from which it standards came met minnesota department of health be sure your answer has the correct number of significant digits.

Maximum allowable mass of cadmium in a 76.0mL sample is 0.304μg (0.304mcg)

Explanation:

In the complete question, the limit for cadmium is defined as 4.00μg/L.

μg can also be denoted as mcg

The concentration of cadmium is the amount of mass of cadmium per unit volume of water. The limit for the mass of cadmium in the measured sample can be found by multiplying the volume of water by the allowed concentration.

93.2 ml + 3920 ml = 4013 ml total  

(93.2 ml) * (2.03 m) / (4013 ml) = 0.0471 m

the volume in in l of the diluted solution would be 0.0471 m.

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
