Do you mean rounding if u do then :
rounding to 1.s.f is 5g
rounding to 2.s.f is 5.4 g
rounding to 3.s.f is 5.43g
A clastic rock is a sedimentary rock consisting of broken pieces of rock like sand grains welded together ie often cemented together by such things as silica or a calcareous cement and also by compaction. Different types of sandstone like quartz sandstone, greywacke, arkose etc are clastic rocks.
Answer : The atomic mass of chlorine is, 36.723 amu
Explanation :
Average atomic mass of an element is defined as the sum of masses of each isotope each multiplied by their natural fractional abundance.
Formula used to calculate average atomic mass follows:
As we are given that,
Mass of 35-Cl isotope = 35 amu
Percentage abundance of 35-Cl isotope = 13.85 %
Fractional abundance of 35-Cl isotope = 0.1385
Mass of 37-Cl isotope = 37 amu
Percentage abundance of 37-Cl isotope = 86.15 %
Fractional abundance of 37-Cl isotope = 0.8615
Now put all the given values in above formula, we get:
Therefore, the atomic mass of chlorine is, 36.723 amu
Answer:
Bothersome pollutants are pollutants that persist in water.
Explanation:
Bothersome pollutants are those pollutants that have deleterious effects on human health which are consistently lodged into water bodies. Bothersome pollutants include petroleum products, heavy metals, and toxic chemicals etc.
Many of these bothersome pollutants are non biodegradable. They accumulate at the bottom of the ocean thereby causing problems for aquatic organisms and disrupting the aquatic ecosystems in the ocean.
These bothersome pollutants are not soluble in water hence we can not just destroy them by dissolving them in water. They persist in the aquatic ecosystem and can even migrate from place to place thereby spreading pollution.
The number of electrons in a neutral atom is equal to the number of protons. The mass number of the atom (M) is equal to the sum of the number of protons and neutrons in the nucleus. The number of neutrons is equal to the difference between the mass number of the atom (M) and the atomic number (Z).
