-What is the wavelength of a 2.28 x 1017 Hz wave?
1 answer:
I attached the working and the answer to both questions below.
Please note that C = speed of light, ν = frequency, λ= wavelength
<span>The wavelength of a 2.28 x 10</span>¹⁷<span> Hz wave is 1.31 </span>×<span> 10</span>⁷ cm<span>
The frequency of a 7.30 x 10</span>⁻⁵<span> m wave 4.11 </span>×<span> 10</span>¹² s⁻¹

60.7 ml is the volume of a sample of CO2 at STP that has a volume of 75.0mL at 30.0°C and 91kPa.
Explanation:
Data given:
V1 = 75 ml
T1 = 30 Degrees or 273.15 + 30 = 303.15 K
P1 = 91 KPa
V2 =?
P2 = 1 atm or 101.3 KPa
T2 = 273.15 K
At STP the pressure is 1 atm and the temperature is 273.15 K
applying Gas Law:
=
putting the values in the equation of Gas Law:
V2 =
V2 =
V2 = 60.7 ml
at STP the volume of carbon dioxide gas is 60.7 ml.
