<u>Answer:</u> The temperature of the solution in Kelvins is 422.356 K
<u>Explanation:</u>
Temperature is defined as the measure of coldness or hotness of a body. It also determines the average kinetic energy of the particles in a body.
This term is expressed in degree Celsius, degree Fahrenheit and Kelvins. All these units are interchangeable.
The S.I unit of temperature is Kelvins.
We are given:
Temperature of a solution = ![149.206^oC](https://tex.z-dn.net/?f=149.206%5EoC)
Conversion used to convert degree Celsius and Kelvins is:
![T(K)=[273.15+T(^oC)]](https://tex.z-dn.net/?f=T%28K%29%3D%5B273.15%2BT%28%5EoC%29%5D)
![T(K)=273.15+149.206\\T(K)=422.356K](https://tex.z-dn.net/?f=T%28K%29%3D273.15%2B149.206%5C%5CT%28K%29%3D422.356K)
Hence, the temperature of the solution in Kelvins is 422.356 K
1.0 mole of gas at STP occupies 22.4 Litres.
4/0L / 22.4 L/mole = 0.179 moles He.
