Question

an organic chemist measures the temperature t of a solution in a reaction flask. here is the result. t = 19.4 °c. convert t to si units. round your answer to 4 significant figures.

Explanation:

Step1: Recall temperature - conversion formula

The formula to convert from Celsius ($T_C$) to Kelvin ($T_K$) is $T_K=T_C + 273.15$.

Step2: Substitute the given value

Given $T_C = 19.4^{\circ}C$, then $T_K=19.4 + 273.15$.

Step3: Calculate the result

$T_K=292.55$ K.

Step4: Round to 4 significant - figures

Rounding 292.55 to 4 significant figures gives 292.6 K.

Answer:

292.6
