The mass of Na22 in the sample is 0.053746 g.
We have a sample with 2 isotopes of sodium. Na22 with a relative atomic mass of 21.9944 u and Na23 with a relative atomic mass of 22.9898 u. Let "x" be the fractional abundance of Na22 and "1-x" the fractional abundance of Na23. If the apparent atomic mass is 22.9501 u, we can state the following expression.
The mass of the sample is 1.3476 g. We can find the mass of Na22 in the sample by multiplying it by its fractional abundance.
The mass of Na22 in the sample is 0.053746 g.

I think they orbit around the atom
When water changes state in the water cycle, the total number of water particles remains the same. The changes of state include melting, sublimation, evaporation, freezing, condensation, and deposition. All changes of state involve the transfer of energy.

Answer:
Bowling ball
Explanation:
They are traveling at the same speed, but the bowling ball has more mass. The bowling ball has more kinetic energy because more force is needed to stop the rolling bowling ball. Two balls with different masses moving at the same speed have different amounts of kinetic energy.
