How is mass calculated given density and volume?

Chemistry

KonstantinChe [14]2 years ago

Taking into account the definition of density, mass can be calculated as the multiplication between density and volume.

<h3> Density</h3>

Density is defined as the property that matter, whether solid, liquid or gas, has to compress into a given space.

In other words, density is a quantity that allows us to measure the amount of mass in a certain volume of a substance.

Then, the expression for the calculation of density is the quotient between the mass of a body and the volume it occupies:

density= mass÷ volume

From this expression it can be deduced that density is inversely proportional to volume: the smaller the volume occupied by a given mass, the higher the density.

<h3>Mass given density and volume</h3>

In this case, you know the density and volume of a compound.

From the definition of density, you can calculate mass as follows:

<u><em>mass= density ×volume</em></u>

In summary, mass can be calculated as the multiplication between density and volume.

5. Which of the following has variable composition<br>A. Water<br>B. sugar<br>C, soil<br>D. Salt​
erica [24]

Answer:

C. Soil

Explanation:

The choice with variable composition is the soil. Soil have many different composition.

  • Soil is made up of minerals, organic matter , water and soil air.
  • Soil minerals are derived from weathered bedrock materials that have been broken down into small pieces.
  • Organic matter is derived from dead and decaying materials from plants and animals.
  • All these materials combine together to form a soil.

Identify the classification of milk a aerosol b solid emulsion c solid aerosol d foam e emulsion
enot [183]

option (c) emulsion is the right answer

Emulsion is a classification of milk.

<h3>Describe an emulsion.</h3>

In physical chemistry, an emulsion is a combination of two or more liquids in which one of the liquids is present as microscopic or ultramicroscopic droplets dispersed throughout the other.

<h3>How is emulsion used?</h3>

Emulsions form as a result of the cleansing action of soaps.

(ii) The emulsification process is how lipids are broken down in the intestines.

(iii) Disinfectants and antiseptics combine with water to generate emulsions.

(iv) The emulsification technique is utilized to create medications.

<h3>How is an emulsion created?</h3>

When two immiscible liquids, such as oil and water, are stirred together with an emulsifier—which might be a protein, phospholipid, or even a nanoparticle—emulsion is created.

15g of magnesium (II) oxide decomposes, find the number of oxygen particles produced at 100% yield.
erastova [34]

2.258625 *10²³ oxygen atoms will be produced.

<h3><u>Explanation:</u></h3>

Decomposition reaction is defined as the type of reaction where one single reactant breaks to produce more than one product only by means of heat or other external factor.

Formula of magnesium oxide = MgO.

The molecular mass of magnesium oxide = 24 +16= 40.

So in 40 grams of magnesium oxide, number of molecules is 6.023 * 10²³.

So in 15 grams of magnesium oxide,, number of molecules is 6.023 *1023 * 15/40 = 2.258625 *10²³.

From one molecule of magnesium oxide, one oxide atom will be produced.

So number of oxide atoms with 100% yeild = 2.258625 *10²³
