Answer:
The answer is 1385 x10∧ -3
Explanation:
Scientific notation is a quick way to represent a number using notation in exponential form or powers of base ten.
This notation allows us to express too large or small numbers easily.
<u>For example:
</u>
500 is written as 5x10∧2; Where the power 2 represents the number of 0's that follow 5.
0.0093 is written as 9.3x10∧-3; Where the power -3 represents the number of times the comma was moved to the right.

Answer:
C. 100.7 amu
Explanation:
Isotopes of an element are atoms of an element with the same atomic number but different atomic masses. Each atomic mass of an isotope is known as an isotopic mass. An element that exhibits isotope, that is, that have two or more isotopes has a relative atomic mass that is not a whole number.
Relative atomic mass of X is the sum of the products of the relative abundances of each isotope and its isotopic mass.
For Isotope ¹⁰⁰X: 30% × 100 = 30 amu
For Isotope ¹⁰¹X: 70% × 101 = 70.7 amu
Relative atomic mass of X = (30 + 70.7) amu = 100.7 amu
Therefore, the approximate atomic mass of X is 100.7 amu
Explanation:
The given data is as follows.
Flow of chlorine (Q) = 
Amount of liter present per day is as follows.
It is given that dosage of chlorine will be as follows.
10 mg/l = 
kg/l
Therefore, total chlorine requirement is as follows.
Total chlorine requirement = 
kg/day
= 100 kg/day
Thus, we can conclude that the kilograms of chlorine used daily at the given water treatment plant is 100 kg/day.
