The formula for determination of atomic mass given the mass of isotopes and relative abundance is:
Ar = ∑(mass * abundance) / 100
Ar = (68.92558 * 60.108 + 70.92470 * 39.892) / 100
Ar = 69.72306
The atomic mass of gallium is 69.72306 amu
Answer:
Abiotic is non living.
Explanation:
An example would be dirt, water, rocks, sand, the sun etc.
Answer:
Hi , your answer is that At impact, the cue ball stops, but transfers all of its momentum and kinetic energy to the other ball, resulting in the hit ball rolling with the initial speed of the cue ball. In an inelastic collision, momentum is conserved, but the total kinetic energy of the system is not conserved
Explanation:
i really hope i helped , pleae give me brainliest , have a nice day and thank you in advance :) .
Answer:
Hey there!
Density=Mass/Volume
Volume: 9.4x8.7x11.5
Volume: 940.47 cm^3
Density of aluminum
2540/940.47, or 2.7 grams/cm^3
Let me know if this helps :)
