<u>Answer:</u> The number of moles of ideal gas are 0.0037 moles
<u>Explanation:</u>
To calculate the mass of helium gas, we use the equation given by ideal gas:
PV = nRT
where,
P = Pressure of helium gas = 52 cmHg = 520 mm Hg (Conversion factor: 1 cm = 10 mm)
V = Volume of the helium gas = 137 mL = 0.137 L (Conversion factor: 1L = 1000 mL)
n = number of moles of gas = ?
R = Gas constant =
T = Temperature of helium gas = (Conversion factor: )
Putting values in above equation, we get:
Hence, the number of moles of gas is 0.0037 moles.
Explanation:
The pH of a weak base falls somewhere between 7 and 10.
your answer should be geothermal power
Answer:
is the volume of the air in the balloon after it is heated.
Explanation:
To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.
Mathematically,
(at constant pressure)
where,
are the initial volume and temperature of the gas.
are the final volume and temperature of the gas.
We are given:
Putting values in above equation, we get:
is the volume of the air in the balloon after it is heated.
