Chemical property of the substance but then again it could be physical
<span>At a depth of 34 feet the diver experiences 2 atmospheres of pressure.
At a depth of 68 feet the diver is experiencing 3 atmospheres.
At a depth of 102 feet the diver is experiencing 4 atmospheres of pressure.
At one atmosphere of pressure the body is mildy compressed. As the diver descends the divers body will undergo increased compression instead of being squashed.</span>
Answer:
0.879 mg
Explanation:
To solve this problem we need to use the definition of ppm:
- ppm = μg solute / g solution
With the above information in mind we can calculate the micrograms of lead using the concentration (13.97 ppm) and mass of solution (62.9 g):
- μg lead = 13.97 ppm * 62.9 g
Finally we convert μg to mg:
- 878.713 μg *
= 0.879 mg of lead
Answer:
For every 1 Ca(NO3)2 there are six (2 * NO3 or 2 * 3 O) oxygens. If you have 3 mole of Ca(NO3)2 then you have 18 mole of oxygen atoms (3*6).
