n = m/M = 15/102.894 = 0.1457811 moles
c = n/V = n / 0.25 = 0.58312438 moles/dm3
Answer:
23.226 psi
Explanation:
From the source,
The mass of the carbon dioxide is:- 16.0 g
Molar mass of carbon dioxide = 44.01 g/mol
The formula for the calculation of moles is shown below:
Thus,
Moles of
= 0.3636 moles
Volume = 3.79 L
n = 0.3636 mol
Temperature = 297 K
Using ideal gas equation as:
PV=nRT
where,
P is the pressure
V is the volume
n is the number of moles
T is the temperature
R is Gas constant having value = 0.0821 L.atm/K.mol
Applying the equation as:
P × 3.79 L = 0.3636 mol × 0.0821 L.atm/K.mol × 297 K
⇒P = 2.34 atm
Also, 1 atm = 14.7 psi
So, Pressure =
psi = 37.926 psi
THus, pressure by the gas is:-
P = Total pressure - Atmospheric pressure = 37.926 - 14.7 psi = 23.226 psi
<u>The carbon dioxide in the cartridge inflate a 3.79 L mountain bike tire to 23.226 psi pressure.</u>
It is 4.18 joules pr gram

Hi there! All of the water returns to the atmosphere, it's called evapotranspiration and condenses. And then the water falls back to the Earth's surface and starts the cycle all over again. If you don't know what I mean, it's the Water Cycle.
The layer that we live in is the Troposphere.
Hope this answer is correct.
