The mass number of an ion with 104 electrons, 158 neutrons, and a +1 charge is 263.
<h3>How to calculate mass number?</h3>
The mass number of an element can be calculated by summing the number of protons and the number of neutrons in the nucleus of the atom.
The proton number is the same as the atomic number of the element.
According to this question, an ion has 104 electrons, 158 neutrons, and a +1 charge. This means that the ion has 105 protons.
Hence, the mass number of the ion will be 105 + 158 = 263.
Therefore, the mass number of an ion with 104 electrons, 158 neutrons, and a +1 charge is 263.

A. Breezes is the correct answer!
The question is incomplete, however, the question is asking about the density of coconut oil by the given data
Answer:
The correct answer is - d = 0.9402
Explanation:
Given:
mass of the coconut oil in cup = 945 gm
the volume of coconut oil in cup = 1.05 liter
solution:
we know that,
volume × density = mass
then, 1.05 × d = 945
d = 945/1005 (converting the liter value to ml)
d = 0.9402 (at room temperature)
The correct answer is - d = 0.9402
