An ideal gas in a closed container initially has a volume V and Temperature T the final tempera is 5/4T and the final pressure i

Anettt [7]

Answer:

$V_2 = \frac{5V}{8}$

Explanation:

I am assuming you are saying what is the final volume of the gas

Known :

Initial volume (V1) = V

Initial temperature (T1) = T

Final temperature (T2) = 5/4 T

Initial pressure (P1) = P

Final pressure (P2) = 2P

<u>Wanted: Final volume (V2)</u>

<u />

<u /> $\frac{P_1V_1}{T_1} = \frac{P_2V_2}{T_2}\\\frac{PV}{T} = \frac{(2P)V_2}{(5/4)T}\\\frac{V}{1} = \frac{(2)V_2}{5/4}\\5/4V = 2V_2\\\\V_2 = \frac{5V}{8}$

Calculate the density of a sample if the mass is 2.98g and the volume is 2.12l

sineoko [7]

Hey there!:

Mass = 2.98 g

Volume = 2.12 L

Therefore:

Density = mass / volume

Density = 2.98 / 2.12

Density = 1.405 g/L
