The mass number of an atom : 26
<h3>Further explanation</h3>
Given
12 protons, 14 neutrons, and 12 electrons
Required
The mass number
Solution
Inside the atom there are 3 sub-particles, namely protons, neutrons and electrons. Protons and electrons are present in the atomic nucleus while electrons move around the atomic nucleus through energy levels in the atomic shell
Atomic number = number of protons = number of electrons
Mass number = number of protons + number of neutrons
Input the value :
Mass number = 12 + 14
Mass number = 26
Rebekah reports the volume of sugar solution using metric system as 39.1 mL. Thus, option D is correct.
The metric system has been the measurement system introduced in 1790s. The system has mediated the units for the measurement of volume, mass, length.
The volume has been the space that has been occupied by matter. The volume can be denoted with SI unit L. However, the another accepted unit for volume has been mL.
Thus, the volume of sugar solution has been reported in mL.
The given sugar solution has volume of 1.32 fl. Oz
The volume in mL can be given as:

The volume of the sugar solution reported by Rebekah on the metric scale has been 39.1 mL. Thus, option D is correct.
