Step-by-step explanation:
The weight of an object is the force exerted on it due to gravity, and its magnitude is measured in newtons (N).
We can calculate the weight of the sodium ion using the formula:
weight = mass x acceleration due to gravity
The mass of the sodium ion is given as 23 u (atomic mass units). One atomic mass unit is defined as one twelfth of the mass of a carbon-12 atom, which is approximately 1.66 x 10^-27 kg.
The acceleration due to gravity on the Earth's surface is approximately 9.8 m/s^2.
So, we can calculate the weight of the sodium ion as:
(23 x 1.66 x 10^-27 kg) x 9.8 m/s^2 = 3.6 x 10^-25 N
Therefore, the magnitude of the weight of the sodium ion is 3.6 x 10^-25 N. Keep in mind that this is a very small value, and the weight of the sodium ion is difficult to measure or detect.
