Answer
$3.14\times10^3J$
Work Step by Step
We will use the formula written below to solve this question:
$W=nRTln\frac{V_f}{V_i}$
But first, we need to convert the temperature to Kelvin:
$T=C^{\circ}+273=30+273=303K$
Since we know the values of $n,R,T, V_f$ and $V_i$, we put these values in the formula and solve for $W$:
$W=1.8(8.314)(303)(\frac{1.5}{3})$
$W=-3140J=-3.14\times10^3J$
Therefore, the amount of energy transferred is $3.14\times10^3J$.
