The formula to convert Celsius (°C) to Kelvin (K) is $K = °C+ 273.15$.

Step2: Substitute the given value

Given $°C = 222$, then $K=222 + 273.15$.

Step3: Calculate the result

$K=495.15$. Since 222 has 3 significant - figures, the answer should also have 3 significant - figures. Rounding 495.15 to 3 significant - figures gives 495 K.
