Answer:

Explanation:
Using the Ideal Gas Law we have
and the number of moles n could be expressed as
, where m is the mass and M is the molar mass.
Now, replacing the number of moles in the equation for the ideal gass law:

If we pass the V to divide:

As the density is expressed as
, we have:

Solving for the density:

Then we need to convert the units to the S.I.:






Finally we replace the values:




Answer:
Na and Cl
Explanation:
An ionic compound is solid at state room temperature. Therefore Na and Cl would be the correct answer :)
Answer:
mass
Explanation:
The amount of kinetic energy an object has, depends on its mass and its speed.
Answer:
1425 mmHg.
Explanation:
The following data were obtained from the question:
Initial volume (V1) = 1.5 L
Initial pressure (P1) = 1 atm
Final volume (V2) = 0.8 L
Final pressure (P2) =?
Next, we shall determine the final pressure of the gas by using the Boyle's law equation as follow:
P1V1 = P2V2
1 × 1.5 = P2 × 0.8
1.5 = P2 × 0.8
Divide both side by 0.8
P2 = 1.5/0.8
P2 = 1.875 atm
Finally, we shall convert 1.875 atm to mmHg.
This can be obtained as follow:
1 atm = 760 mmHg
Therefore,
1.875 atm = 1.875 × 760 = 1425 mmHg.
Therefore, the new pressure of the gas is 1425 mmHg.
Explanation:
(a) The given data is as follows.
Pressure on top (
) = 140 bar =
(as 1 bar =
)
Temperature =
= (15 + 273) K = 288 K
Density of gas = 


= 0.4548

=
= 
Hence, pressure at the natural gas-oil interface is
.
(b) At the bottom of the tank,

= 2.206 \times 10^{7} Pa + 700 \times 9.81 \times (6000 - 4700)[/tex]
= 
= 309.8 bar
Hence, at the bottom of the well at
pressure is 309.8 bar.
