Using ideal gas equation,
Here,
P denotes pressure
V denotes volume
n denotes number of moles of gas
R denotes gas constant
T denotes temperature
The values at STP will be:
P=1 atm
T=25 C+273 K =298.15K
V=663 ml=0.663L
R=0.0821 atm L mol ⁻¹
Mass of gas given=1.25 g g
Molar mass of gas given=?
Putting all the values in the above equation,
Molar mass of the gas=46.15
Answer:
a) Yes, these bands of signals overlap.
b) FM has broader transmission band.
Explanation:
a) Frequency range of TV channels = 59.5 to 215.8 MHz
Wavelength range of FM radio = 2.78 m to 3.41 m
Frequency of the wave =
Wavelength of the wave =
Speed of light = c =
Frequency of wave with,
Frequency of wave with,
Frequency range of FM = 87.89 to 107.9 MHz
Frequency range of TV channels = 59.5 to 215.8 MHz
Yes, these bands of signals overlap.
b)
Frequency range of AM = 550 to 1600 kHz
1 kHz = 0.001 MHz
550 to 1600 kHz = to
= 0.55 MHz to 1.6 MHz
Frequency range of AM = 0.55 to 1.6 MHz
Frequency range of FM = 87.89 to 107.9 MHz
FM has broader transmission band.
