Answer:
The correct answer is 3.6 L
Explanation:
According to the gases Boyle's law, the relation between the volume and the pressure of a gas at constant temperature is given by the following mathematical expression:
Pi x Vi = Pf x Vf
Where Pi and Vi are the <u>initial </u>pressure and volume of the gas whereas Pf and Vf are the <u>final</u> pressure and volume, respectively.
In this problem we have:
Vi = 18.0 L
Pi= 902 Torr
Pf= 4510 Torr
The final volume (Vf) will be:
Vf = (Pi x Vi)/Pf = (902 Torr x 18.0 L)/4510 Torr= 3.6 L
From the result, we can see that if the pressure increases, the volume of the gas decreases.
Answer:
A mole is an amount of a substance that contains 6.022✖️10^22 atoms of that substance
Or
Gram atomic masses,gram formula masses or gram formula masses are called one mole.
Molar solution or molarity is defined as the number of miles of so lutes dissolved per dm^3 of solution

Answer:
c. lava
if u know about rock formation for igneous rock is formed from lava and when cool it becomes rock
A mirror is opaque, meaning that it reflects the light and images that shine on it's reflective surface.
I am assuming that the problem ask for the pressure in
the system. To be able to calculate this, we first assume that the system acts
like an ideal gas, then we can use the ideal gas equation to find for pressure
P.
P V = n R T
where,
P = Pressure (unknown)
V = 0.17 m^3
n = moles of lng / methane
R = gas constant = 8.314 Pa m^3 / mol K
T = 200 K
We find for the moles of lng. Molar mass of methane = 16
kg / kmol
n = 55 kg / 16 kg / kmol
n = 3.44 kmol CH4 = 3440 mol
Substituting all the values to the ideal gas equation:
P = 3440 mol * (8.314 Pa m^3 / mol K) * 200 K / 0.17 m^3
P = 33,647,247 Pa
