The answer is B because if you don't have water on your body you won't live right, and if you don't have water on your body your cells won't work that well.
I HOPE THIS HELP!!
Explanation: Entropy decreases when the number of moles of gas decreases during a reaction. In the case of the correct answer, the number of moles of gas decreases from two to one. When a substance goes from a solid to a gas (sublimation) or from a liquid to a gas (evaporation), entropy increases.
I have used the equation of real gas
Molarity is number of moles of solute per one liter of solution. The symbol for molarity is a capital M. The molarity of the given solution will be 3.125M
A solution is a mixture of two or more substances in which neither of substance changes chemically. For example, the salt water is a solution that contains the water (the solvent) and salt (the solute). Concentration is amount of dissolved substance in a solution. In other words, it is amount of stuff that has been mixed into the liquid. Concentration is usually measured in the molarity.
Given that,
Number of moles= 1
Volume = 320ml= 0.320 L
Molarity= No of moles of solute/ Volume of solution in L
= 1/ 0.320
= 3.125 M

As we know, Number of protons = Atomic Number
So,
And, Atomic mass = Number of protons + Number of Neutrons (N)
therefore ~
Number of Neutrons = 19
