Chemistry

By dividing the percentage composition with the molar mass of that element we will get the empirical formula. Then using that empirical formula and formula mass we can find the molecular formula.

<u>Explanation:</u>

The chemical properties of any substance are defined obviously by the different types and relative amounts of atoms constituting its primary entities (in case of covalent compounds the primary entities are molecules and ions in the event of ionic compounds).

A percent composition of any compound gives the mass percent of each element present in the compound; in addition to that frequently it is determined experimentally and utilized to derive an empirical formula of any compound. An empirical formula mass of any covalent compound could be comparable with the molar or molecular mass of a compound to acquire a molecular formula.

leonid [27]

Answer:

1.1 mol/liter

Explanation:

You would use the M1V1 = M2V2 equation to solve this.

We know M1 is 3.0 M, V1 is 25 milliliters, and V2 is 68 milliliters. We need to find M2.

To find M2, first plug in what you know.

(3.0 M)(25 mL) = M2(68 mL)

Then, divide everything by 68 mL to get M2 by itself

Your answer should be a quite large decimal but I rounded it to 1.1 mol/liter.

What is the net charge of the ionic compound calcium fluoride
yKpoI14uk [10]

Answer:

  • <em>The net charge of the ionic compound calcium fluoride is </em><u><em>zero (0).</em></u>

<em>Explanation:</em>

<em>Ionic compounds,</em> such as covalent ones, have zero net charge; this is, they are neutral.

Substances with net positive charge are cations and substances with net negative charge are anions.

The charges in the <em>ionic compound calcium flouride</em> are distributed in this way:

  • Compound formula: CaF₂

  • Calcium charge: Ca²⁺: this is, each calcium ion has a 2 positive charge

  • Fluoride charge: F⁻: each fluoride ion has a 1 negative charge.

  • Then, the <em>net charge</em> is: 1 × (2+) + 2 × (1-) = +2 - 2 = 0.

So, a two positve charge, from one calcium ion, is equal to two negative charges, from two fluoride tions, yielding a <u>zero net charge</u>.
