Dividing the mass of the water lost by the mass of hydrate used is equal to the fraction of water in the compound. Multiplying this fraction by 100 gives the percent water in the hydrate.
How to find it?
Divide the mass of the water lost by the mass of hydrate and multiply by 100. The theoretical actual percent hydration percent water can be calculated from the formula of the hydrate by dividing the mass of water in one mole of the hydrate by the molar mass of the hydrate and multiplying by 100.
Before making any observations, deductive reasoning relies on the formulation of a hypothesis and its subsequent substantiation.
<h3>Deductive reasoning: What does it mean?</h3>
Since the sentence states that "he assumes will apply to all instances," he is suggesting something before to carrying out any observation, which is the foundation of deductive reasoning.
A conclusion in deductive reasoning is based on the agreement of several premises that are typically taken to be true. Sometimes, top-down logic is used to describe deductive reasoning. Making logical assumptions is the foundation of deductive reasoning, which then bases a conclusion on those assumptions.
The primary distinction between inductive and deductive thinking is that the former tries to develop a hypothesis, whilst the latter aims to test an existing theory. From specific observations, inductive reasoning proceeds to

Answer:
The mass of the nucleus is almost the same as the atom because a majority of the mass of an atom is stored in the nucleus.
The volume of an atom is larger than the nucleus. The nucleus is a tiny, concentrated area inside of the atom. Atoms are mostly empty space inside.
Explanation:
Silicon (Si) atomic mass is 28.085.
To find the mass number of most common isotope we need to round atomic mas to wholes.
28.085≈28 is atomic mass
Atomic number(number of protons) is an ordinal number of an element in the Periodic Table.
For silicons it is 14.
Mass number=number of protons(atomic number)+number of neutrons.
Number of neutrons=Mass number - Number of Protons(atomic number)
Number of neutrons= 28 - 14 = 14
Correct answer is B.14
