The average atomic mass of Rubidium : 85.556 u
<h3>Further explanation</h3>
Isotopes are atoms that have the same atomic number but different mass numbers
Each isotope has an abundance which is usually expressed as a percentage
The average relative mass of atoms is obtained by adding the product of the percentage and mass of each isotope
Can be formulated:
The abundance of 85 Rb is 72.2% and the abundance of 87 Rb is 27.8%, so
mass isotope 1=85, %abundance=72.2
mass isotope 2=87, %abundance=27.8
The averages atomic mass of Rubidium :
Answer:
<h2><em>
The answer is</em> B. Gas particles have a large volume relative to the spaces between them. </h2><h2 />
Answer:
The answer is c. A + BC → AC + B
Answer:
Hi! It's B - globular cluster
Intensity has no affect on whether or not the photoelectric effect occurs. The determining property is frequency and since frequency and wavelength are inversely proportional, wavelength matters as well. If a frequency of light can't cause the photoelectric effect to happen, no matter what the intensity is, the light can't make it happen.
I hope this helps. Let me know in the comments if anything is unclear.
