Answer:

Explanation:

An internal force acts between elements of the system. Only external forces affect the motion of a system, according to Newton's first law.

A sample of carbon dioxide gas occupies a volume of 250 mL at 25c what volume will it occupy at 95c

anzhelika [568]

Considering the Charles's law, the sample of carbon dioxide gas will occupy 308.72 mL.

<h3>Charles's law</h3>

Charles's law establishes the relationship between the temperature and the volume of a gas when the pressure is constant. This law says that the volume is directly proportional to the temperature of the gas: for a given sum of gas at constant pressure, as the temperature increases, the volume of the gas increases and as the temperature decreases, the volume of the gas decreases.

Mathematically, Charles's law states that the ratio between volume and temperature will always have the same value:

$\frac{V}{T} =k$

Considering an initial state 1 and a final state 2, it is fulfilled:

$\frac{V1}{T1} =\frac{V2}{T2}$

<h3>Final volume in this case</h3>

In this case, you know:

V1= 250 mL
T1= 25 C= 298 K (being 0 C=273 K)
V2= ?
T2= 95 C= 368 K

Replacing in Charles's law:

$\frac{250 mL}{298 K} =\frac{V2}{368 K}$

Solving:

$V2=368 K\frac{250 mL}{298 K}$

<u><em>V2= 308.72 mL</em></u>

Finally, the sample of carbon dioxide gas will occupy 308.72 mL.

Is atomic weight a whole number or not a whole number

steposvetlana [31]

Answer:

Atomic mass of an element is not a whole number because It contains isotopes. For example, chlorine has two isotopes 1735Cl and 1737Cl with natural abundances in the approximate ratio of 3:1. Hence, the average atomic mass of chlorine is approximately 35.5 g/mol.

Hope this helps! If so please mark brainliest and rate/heart if it did to help my account out!!
