Question

a student sets up the following equation to convert a measurement. (the ? stands for a number the student is going to calculate.) fill in the missing part of this equation. (0.080 (\frac{j}{mol})) (cdot) (square) = ? (\frac{kj}{mol})

Explanation:

Step1: Recall the conversion factor between joules and kilojoules

We know that $1\ kJ = 1000\ J$, or $\frac{1\ kJ}{1000\ J}=1$.

Step2: Multiply the given value by the conversion factor

We have $0.080\frac{J}{mol}$. To convert joules per mole to kilojoules per mole, we multiply by $\frac{1\ kJ}{1000\ J}$. So, $0.080\frac{J}{mol}\times\frac{1\ kJ}{1000\ J}=\frac{0.080}{1000}\frac{kJ}{mol}= 8\times10^{-5}\frac{kJ}{mol}$.

Answer:

$8\times10^{-5}$
