The tolerance of a Class A \( 25 \mathrm{~mL} \) transfer pipet is \( \pm 0.03 \mathrm{~mL} \). A student uses an uncalibrated Class A transfer pipet to deliver a total of \( 125 \mathrm{~mL} \) of solution. What is the uncertainty in the delivered \( 125 \mathrm{~mL} \) ? Incorrect Next, the student calibrates the pipet. The calibrated pipet delivers a mean volume of \( 24.994 \mathrm{~mL} \) with an uncertainty of \( \pm 0.004 \mathrm{~mL} \). The student then uses the calibrated \( 25 \mathrm{~mL} \) pipet to deliver a total of \( 124.970 \mathrm{~mL} \) of solution. What is the uncertainty in the delivered \( 124.970 \mathrm{~mL} \) ?
