Answer:
35.45 amu is the average atomic mass of chlorine.
Explanation:
The average atomic mass is given :
Atomic mass of 35-Cl = 34.968 amu
Percentage abundance of 35-Cl = 75.53%
Fractional abundance of 35-Cl = 0.7553
Atomic mass of 37-Cl = 36.956 amu
Percentage abundance of 37-Cl = 24.47%
Fractional abundance of 37-Cl = 0.2447
Average atomic mass of chlorine:
35.45 amu is the average atomic mass of chlorine.
Answer: 2,3 * 4 = 9,2
Explanation:
If 1 mole CH4 has 4 H atoms 2,3 moles of CH4 will have 9,2 H atoms.
<span>Conductance gives a more accurate method to determine the salt concentration of a solution.Conductivity would be used with conductors such as metals that include copper and silver.Conductivity is a measure of water's capability to pass electrical flow. This ability is directly related to the concentration of ions in the water. These conductive ions come from dissolved salts and inorganic materials such as alkalis, chlorides, sulfides and carbonate compounds</span>
