Hey there !:
Molarity is the amount of solute, in mol, dissolved in a volume of solution in Liters , so:
Moles of solute = 0.50 mol
Volume of solution = 6.50 L
Therefore:
Molarity = moles of solute / volume of solution
Molarity = 0.50 / 6.50
Molarity = 0.0769 M
Hope that helps!
The error in the student's reasoning happened as they get confused between the beta minus decay and beta plus decay.
<h3>What is beta minus decay?</h3>
A neutron is converted into a proton in beta minus, increasing the atomic number of the atom.
- The proton is positive, while the neutron is neutral.
- The nucleus also produces an electron and an antineutrino in order to ensure charge conservation.
In the given question beta minus decay is not occur as atomic number of the daughter nuclei does not increases. Rather than this in the given decay atomic mass of the daughter nuclei is less than the parent nuclei means plus beta decay is happened there.
Hence the error is in predicting the correct particle with charge.

Answer:
The density of this solution is 2.2 g/mL
Option 3 is correct
Explanation:
Step 1: Data given
Volume = 10.0 mL
mass = 22 grams
Step 2: Calculate the density
Density = Mass / volume
Density = 22.00 grams / 10.0 mL
Density = 2.2 grams / mL
The density of this solution is 2.2 g/mL
Option 3 is correct

Answer: The molecule is expected to have a dipole moment of zero.
Explanation:
The product of magnitude of the charge calculated in electrostatic units is called dipole moment.
Formula for dipole moment is as follows.
Dipole moment = Charge (in esu) distance (in cm)
Non-polar molecules have zero dipole moment.
For example, is a non-polar molecule so its dipole moment is zero.
is a polar molecule so it will have dipole moment.
is a polar molecule so it will have dipole moment.
has nitrogen atom as more electronegative than hydrogen atom. So, net dipole moment will be in the direction of nitrogen atom.
Thus, we can conclude that the molecule is expected to have a dipole moment of zero.
