How many molecules of N2O4 are in 76.3g N2O4? The molar mass of N2O4 is 92.02 g/mol.
Murrr4er [49]

Answer:

4.99*10²³ molecules of N₂O₄ are in 76.3 g of N₂O₄

Explanation:

Avogadro's Number is the number of particles that make up a substance (usually atoms or molecules) and that can be found in the amount of one mole of said substance. Its value is 6.023*10²³ particles per mole. Avogadro's number represents a quantity without an associated physical dimension. Avogadro's number applies to any substance.

You know that the molar mass of N₂O₄ is 92.02 g/mol, and you have 76.3 g. Then you can apply the following rule of three: 92.02 grams are present in 1 mole of the compound, 76.3 grams in how many moles are they?

amount of moles= \frac{76.3 grams*1 mole}{92.02 grams}

amount of moles= 0.83 moles

Then, you can apply another rule of three: if by definition of Avogadro's number 1 mole of the compound has 6.023*10²³ molecules, 0.83 moles of the compound, how many molecules will it have?

amount of molecules= \frac{0.83 moles*6.023*10^{23}molecules }{1 mole}

amount of molecules= 4.99*10²³

<u><em>4.99*10²³ molecules of N₂O₄ are in 76.3 g of N₂O₄</em></u>

An important Similarly between photosynthesis and cellular respiration is that both process
adelina 88 [10]

Answer:

Similarity between photosynthesis and cellular respiration is that both process :

<u>Involve production of energy </u>

<u>Exchange of gases</u>

<u>Goes through electron chain reactions</u>

<u></u>

Explanation:

<u>Photosynthesis</u> : It is the process in which green plants containing chlorophyll prepare their food in the presence of Sunlight , water and carbon dioxide.This process occur inside chloroplast .

Here Food is prepared.Oxygen and food is produced as a result of photosynthesis .

<em><u>The electrons triggers the reaction of food formation</u></em>.

<em><u>Energy is released during photosynthesis.</u></em>

<em><u>Gaseous exchange between CO2 and O2 occur.</u></em>

<u>Respiration </u>:

It is the process in which living organism converts oxygen and food to water and carbon dioxide . Here energy is released in the form of ATP. It take place inside the mitochondria of the cell.

<u><em>Exchange of Gases occur between organism and environment.</em></u>

<em><u>Here , mitochondrial electron transport occurs to produce ATP</u></em>.

Hence , similarity between photosynthesis and cellular respiration is that both process:

<u>Involve production of energy </u>

<u>Exchange of gases(carbon dioxide and oxygen)</u>

<u>Goes through electron chain reactions</u>

A sealed piston contains 400 mL of air at standard ambient pressure. The piston is
nydimaria [60]

Answer:

324.24 kPa

Explanation:

Given that;

Initial pressure P1 = 101325 Pa

V1= 400 ml

P2 = ?

V2= 125mL

From Boyle's law;

P1V1 = P2V2

P2 = P1V1/V2

P2= 101325 × 400/125

P2= 324.24 kPa
