Answer:
Volume would be 13
Explanation:
Divide the mass by the density
65/5
Answer:
Below!
Explanation:
Isotopes are elements with a similar chemical makeup and the same atomic number, but a different atomic mass and number of neutrons . An example of this would be carbon-12, carbon-13, and carbon-14. Three isotopes of the element carbon that have the same 6 protons but have a different neutron count. A simple way to explain isotopes would be to say that they are just different "versions" of an element.
Hope this helps ya! Best of luck <3
The percentage abundance of 6Y is 0.102.
An Isotope refers to two or more atoms that has the same atomic number but different mass numbers.
We have been informed from the question that the atomic mass of the element is 6.9412 amu.
Let the abundance of isotope 6Y be x
Let the abundance of isotope 7Y be 1-x
Hence;
6.9412 = 6.015123x + 7.016005(1 - x)
6.9412 = 6.015123x + 7.016005 - 7.016005x
6.9412 - 7.016005 = 6.015123x - 7.016005x
-0.102 = -1x
x = -0.102/-1
x = 0.102
Hence the percentage abundance of isotope 6Y is 0.102.
