How many moles is ( 1 x 10^9 ) molecules O2

Chemistry
1 answer:
Effectus [21]3 years ago
4 0

Answer:

The answer is

1.66 \times  {10}^{ - 15}  \:  \: moles

Explanation:

To find the number of moles in a substance given it's number of entities we use the formula

n =  \frac{N}{L}   \\

where n is the number of moles

N is the number of entities

L is the Avogadro's constant which is

6.02 × 10²³ entities

From the question we have

n =  \frac{1 \times  {10}^{9} }{6.02 \times  {10}^{23} }  \\

We have the final answer as

1.66 \times  {10}^{ - 15}  \:  \: moles

Hope this helps you

What is a technique for determining an unknown molaritry of acid by adding a base of know malarkey to a known volume of acid
bagirrra123 [75]

Titration is a technique for determining unknown molarity of acid by adding a base of know malarkey to a known volume of acid

The process of calculating the quantity of a material A by adding measured increments of substance B, the titrant, with which it reacts until exact chemical equivalency is obtained (the equivalence point)" is the definition of titration. Titration, commonly referred to as titrimetry, is a method of chemical qualitative analysis used to determine the concentration of a certain analyte in a mixture. The goal of titration is to identify the equivalence point, or the point at which chemically equivalent amounts of the reactants have been combined, which is a key analytical chemistry technique also known as volumetric analysis. The stoichiometry of the reactants determines how many reactants have been mixed at the equivalence point.

At 6pm, you see logs piled up for a campfire. Later you see flames and feel heat from it. At 8pm, only smoldering ashes remain.
mr_godi [17]

The process that took place is called oxidation or burning where wood was burnt into ashes.

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

Wood is an organic compound formed of different types of carbohydrates, proteins and lipids. These components do have carbon oxygen hydrogen as most abundant atoms and also has some amount of nitrogen, phosphorous, and other metal ions like magnesium, calcium etc.

When the logs were burnt, the chemical reaction took place between the atmospheric oxygen and the atoms present in the wood, forming different oxides. As carbon was the most abundant atom present, a huge smoke containing carbon dioxide and carbon monoxide evolved. The hydrogen became the water vapour, and other gases were also formed like nitrogen dioxide, sulphur dioxide etc. These gases went off into atmosphere. The rest that were left behind were mixture of unburnt part of wood as well as the solid metal oxides. There were unburnt particles of carbon mixed with them too.
