Answer:
Chlorine --> 89%
Explanation:
Step 1) Add each element's amu up to get the total mass of the compound.
12.011+1.008+3(35.453) = 119.378.
Step 2) Divide the total mass of chlorine by the total mass of the compound.
3(35.453) = 106.359
106.359/119.378 = 0.8909430548.
Step 3) Now multiply by 100 to get the percentage.
0.8909430548*100 = 89.09430548%
Step 4) Estimate and submit your answer
89.09430548% estimates to 89%
Answer:
Yes
Explanation:
Atoms are generally classified as pure substances. A pure substance has the following properties:
- All parts are the same throughout i.e. homogeneous
- They have definite composition
- The cannot easily be broken down into simpler substances by physical means.
- Separation by physical methods is not easy.
- They have unique sets of physical properties.
Elements and compounds are generally classified as pure substances. Since atoms are the building blocks of pure substances, they can be classified as one.

I believe the complete
given is that the bucket of sand contains 9.5 billion grains of sand. That is:
bucket = 9,500,000,000
grains
and the concentration of
brown sand is 2 ppm:
concentration brown sand =
2 / 1,000,000
Therefore:
brown sand = 9,500,000,000
* (2 / 1,000,000)
<span>brown sand = 19,000 grains</span>
