Answer
From $339.5\text{ mL}$ to $340.5\text{ mL}$
Work Step by Step
The measurement is given to the nearest milliliter, so the error is $\pm\text{ 0.5 mL}$. Therefore, to find the range of values that the measurement represents, we must both subtract and add $0.5$ to the given value. $$340+0.5=340.5$$$$340-0.5=339.5$$ Therefore the range of values is from $339.5\text{ mL}$ to $340.5\text{ mL}$
