The molar mass of the gas is 35. glmol.

the molar mass of a chemical compound is described as the mass of a sample of that compound separated by the amount of substance in that sample, measured in moles.

The molar mass is a bulk, not molecular, effects of a substance.

<h3>What is molar mass and how is it calculated?</h3>

The molar mass is the mass of one mole of a sampling. To find the molar mass, count the atomic masses (atomic weights) of all of the atoms in the molecule. Find the atomic mass for each element by using the mass shown in the Periodic Table or table of atomic weights.

<h3>What is molar ?</h3>

Molar refers to the unit of concentration molarity, which is equivalent to the number of moles per liter of a solution. In chemistry, the word most often guides to molar concentration of a solute in a solution. Molar attention has the units mol/L or M.

How do newtons 3 laws relate ​
Lina20 [59]

Like all objects, rockets are governed by Newton's Laws of Motion. The First Law describes how an object acts when no force is acting upon it. So, rockets stay still until a force is applied to move them. Newton's Third Law states that "every action has an equal and opposite reaction".

A solution of NaF is added dropwise to a solution that is 0.0144 M in Ba 2 . When the concentration of F - exceeds __________ M,
Stella [2.4K]

Answer:

When [F⁻] exceeds 0.0109M concentration, BaF₂ will precipitate

Explanation:

Ksp of BaF₂ is:

BaF₂(s) ⇄ Ba²⁺(aq) + 2F⁻(aq)

Ksp = 1.7x10⁻⁶ = [Ba²⁺] [F⁻]²

The solution will produce BaF₂(s) -precipitate- just when [Ba²⁺] [F⁻]² > 1.7x10⁻⁶.

As the concentration of [Ba²⁺] is 0.0144M, the product [Ba²⁺] [F⁻]² will be equal to  ksp just when:

1.7x10⁻⁶ = [Ba²⁺] [F⁻]²

1.7x10⁻⁶ = [0.0144M] [F⁻]²

1.18x10⁻⁴ = [F⁻]²

0.0109M = [F⁻]

That means, when [F⁻] exceeds 0.0109M concentration, BaF₂ will precipitate
