How many grams are in 2.4 moles of sulfur?

Answers

Answer 1

Answer:

According to the mole concept, there are 76.94 g in 2.4 moles of sulfur atoms.

What is a mole?

Mole is defined as the unit of amount of substance . It is the quantity measure of amount of substance of how many elementary particles are present in a given substance.

It is defined as exactly 6.022×10²³ elementary entities. The elementary entity can be a molecule, atom ion depending on the type of substance. Amount of elementary entities in a mole is called as Avogadro's number.

It is widely used in chemistry as a suitable way for expressing amounts of reactants and products.For the practical purposes, mass of one mole of compound in grams is approximately equal to mass of one molecule of compound measured in Daltons. Molar mass has units of gram per mole . In case of molecules, where molar mass in grams present in one mole of atoms is its atomic mass.

Mass is found out by number of moles by formula , mass=number of moles×molar mass

Substitution in above formula gives, mass=2.4×32.06=76.94 g

Thus, there are 76.94 g in 2.4 moles of sulfur.

Answer 2

Answer: Use the equation
Given molesX Molar Mass(g)/1 mol= Mass in grams
2.4 moles X 32.065/1
76.96 Grams :)

Gas - Liquid - Solid

Explanation:

If you are asking which state of matter is more dense of which, then this is the order.

- Liquid is more dense than Gas

- Solid is more dense than Liquid

- Gas is less dense than Air

Just to let you know, Solid is the most dense of them all, making Gas the least dense of the three.

Hope this helps! ^^

solids have more dens than any type of matter and I am sure btw

28 Which compound yields H + ions as the only positive ions in an aqueous solution?(1) KOH (3) CH3OH(2) NaOH (4) CH3COOH

Answers

The compound that yields H+ as the only positive ions when in solution are generally acidic.

Definition of acids

Acids are generally defined as substances that produce hydrogen ions as their only positive ions in aqueous solutions.

Going by this definition, only CH3COOH is able to ionize in an aqueous solution according to the following:

CH3COOH ---------> CH3COO- + H+

Others ionize to give positive ions other than H+.

Answer: (4) $CH_3COOH$

Explanation:-

According to Arrhenius concept, a base is defined as a substance which donates hydroxide ions $(OH^-)$ when dissolved in water and an acid is defined as a substance which donates hydronium ions $(H_3O^+)$ in water.

1. $KOH$ is a strong electrolyte and thus dissociate in water. $KOH\rightarrow K^++OH^-$

2. $CH_3OH$ is a non electrolyte and thus do no dissociate in water.

$CH_3COOH\rightarrow no reaction$

3. $NaOH$ is a strong electrolyte and thus dissociate in water.

$NaOH\rightarrow Na^++OH^-$

4. $CH_3COOH$ is a weak electrolyte and thus partially dissociate in water.

$CH_3COOH\rightleftharpoons CH_3COO^-+H^+$
