Answer:
20.2 amu.
Explanation:
Let A represent isotope ²⁰X
Let B represent isotope ²²X
From the question given above, the following data were obtained:
For Isotope A (²⁰X):
Mass of A = 20
Abundance (A%) = 90%
For Isotope B (²²X):
Mass of B = 22
Abundance (A%) = 10%
Relative atomic mass (RAM) =?
The relative atomic mass (RAM) of the element can be obtained as follow:
RAM = [(Mass of A × A%)/100] + [(Mass of B × B%)/100]
RAM = [(20 × 90)/100] + [(22 × 10)/100]
RAM = 18 + 2.2
RAM = 20.2 amu
Thus, relative atomic mass (RAM) of the element is 20.2 amu
Answer:
movement of particles of object from one place to another
e.g
spreading of perfume in air
spreading of ink in water
Explanation:
The answer to is all the information on a line graph is as precise as the information in the data table would be FALSE
Hey there!
3d band can hold as many as 10 electrons, while 4s can bear as many as two electrons.
The maximum number of electrons for this composite band should be 12 electrons.
Hope that helps!
