PV = nRT. If P = 1 atm, V = 5.0 liter, R = 0.0821 L.atm/mol.K, and T = 293 K; what is the value of n?
Leya [2.2K]

Answer:

n = 0.207 mole

Explanation:

We have,

P = 1 atm

V = 5 liter

R = 0.0821 L.atm/mol.K

T = 293 K

We need to find the value of n. The relation is as follows :

PV = nRT

Solving for n,

n=\dfrac{PV}{RT}\\\\n=\dfrac{1\times 5}{0.0821 \times 293}\\\\n=0.207\ \text{mol}

So, the value of n is 0.207 mol.

I will brainliest you if you answer my question thank you pls read the photo.​
kati45 [8]

Answer:

The flow of information from the starting material DNA to the final product protein is depicted in the core dogma of molecular biology. That is depicted in the diagram. It also shows where each step takes place. Replication is the process of passing information from one DNA to another DNA, as seen in the diagram. This occurs within the nucleus. Why is each process carried out in a certain location? It is because it is where the essential substance may be found. As a result, replication occurs in the nucleus, where the necessary enzymes and ingredients for replication are present.

I hope I helped! ^-^
