<h2>Answer:</h2>

<u>Molar mass</u> is also known as number of grams/mole of something.

<h2>Explanation:</h2>

A substance's molar mass is defined as substance mass divided by the substance amount in moles. It is expressed in Kg/mol but gram/mol is used for the convenience for study.

It is often used in chemistry for the conversion of mass in grams to substance moles. The relation that is used to convert the gram top mole is that the molar mass is equal to the molecular mass in grams.

Answer:

Molar mass

Explanation:

This is a counting unit which represents the mass in grams of a substance that make up one mole of the substance. This mass is calculated as follows:

Molar mass = Mass/ Number of moles

Units: grams/mol

What is the indicator of the number of ions in solution?
Andru [333]

Answer:

The amount of solute added.

Explanation:

The amount of solute added is directly proportional to the number of ions.

The higher the amount added the higher the number of moles.

The number of moles is multiplied by the Avogadro's constant to get the number ions.

No of ions= No of moles × L

L is the Avogadro's number.

A weak acid (ha) has a pka of 4.001. If a solution of this acid has a ph of 4.110, what percentage of the acid is not ionized? (
OverLord2011 [107]

99.9224 % of the acid is not ionized.

____HA + H₂O ⇌ A⁻ + H₃O⁺

I: ___<em>c</em> ________0 ____0  

C: _-α<em>c</em> _______+α<em>c</em> __+α<em>c </em>

E: <em>c</em>(1-α) _______α<em>c</em> ___α<em>c </em>

pH = 4.110

[H₃O⁺] = α<em>c</em> = 10^(-4.110) mol/L = 7.76 × 10⁻⁵ mol/L

α = 7.76 × 10⁻⁵

1 – α = 1 - 7.76 × 10⁻⁵ = 0.999 224 = 99.9224 %

Natali [406]

The mass of dissolved sodium carbonate is 109 g of Na₂CO₃.

<h3>What is a solution ?</h3>

A solution consists of two elements , a solute and a solvent .

A solute is dissolved into solvent to make a solution.

The concentration of a solution is measure by Molarity , Molality , mass% etc.

It is given in the question that

sodium carbonate ( Na₂CO₃) is sometimes used as a water-softening agent

a worker prepares a 0.724 m solution of  Na₂CO₃ and water.

the volume of the solution is 1.421 liters.

Mass of dissolved sodium carbonate is grams =?

Concentration = 0.724 M

Volume = 1.421 liters

Molecular mass of  Na₂CO₃  = 106 g

The mass of the solute needs to be determined

Molarity = moles / volume\

moles = Molarity x volume

Substituting the values

moles = 0.724 x 1.421

moles = 1.029

1 mol of Na₂CO₃ means  106 gm of  Na₂CO₃

Then 1.029 moles will mean 1.029 * 106

109.07 gm

Therefore , the mass of dissolved sodium carbonate is 109 grams.

A. List the potential acute health effects.
AleksandrR [38]

When we handle chemical substances we must be very careful because they can put our:

  • Physical integrity.
  • Health
  • Life at risk.

<h3>What is a chemical?</h3>

A chemical substance is a chemical compound resulting from the union of two or more chemical elements. Compounds have different uses depending on their properties. However, some can be harmful and life-threatening to humans.

<h3>Potential acute effects.</h3>

The potential acute effects of some compounds may be related to skin contact causing:

  • Inflammation
  • Redness
  • Rash
  • Burns
  • Dry
  • Among other.

On the other hand, the chronic effects of chemical compounds can be:

  • Diseases in the central nervous system.
  • Respiratory diseases.
  • Skin diseases.
  • Degenerative diseases of the bone system.

<h3>What to do when a chemical is ingested?</h3>

There are a large number of chemical substances and each one has different properties. Therefore, it is very difficult to generalize about a treatment in case of ingestion. What must be done is to know the level of risk of the substance that is being handled and avoid ingesting it at all costs. However, if it is ingested, go to the emergency room.

<h3>Product flammability</h3>

Not all chemical compounds have the same flammable response to fire. Due to the above, it is necessary to identify if the substance that we are handling is highly or slightly flammable, for this we can consult the manual of the substance or the label of its packaging.

<h3>3 Chemical that produces a potentially dangerous reaction with hydrochloric acid.</h3>

According to some studies and the hydrochloric acid safety data sheet, it can have dangerous reactions with:

  • Reacts violently with water.
  • Gives off hydrogen in reaction with metals.
  • Keep away from strong bases.

<h3>How to handle small spills?</h3>
  • Contain the spill.
  • Soak up with inert absorbent material.
  • Prevent the product from entering the sewage system.
  • Keep in suitable, closed containers for disposal.

<h3>Personal Protection</h3>

When we handle chemical substances we are facing a potential risk. Due to the above, protocols have been developed for its handling, which include the use of protection elements such as:

  • Gloves
  • Glasses
  • Helmet
  • Mask
  • Boots
  • Special suit.
  • Among others.
