<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 = $149.206^oC$

Conversion used to convert degree Celsius and Kelvins is:

$T(K)=[273.15+T(^oC)]$

$T(K)=273.15+149.206\\T(K)=422.356K$

Hence, the temperature of the solution in Kelvins is 422.356 K
