The tolerance of a Class A 25 mL transfer pipet is +0.03 mL. A student uses an uncalibrated Class A transfer pipet to deliver a total of 125 mL of solution. What is the uncertainty in the delivered 125 mL? 0.15 mL 土 Next, the student calibrates the pipet. The calibrated pipet delivers a mean volume of 24.995 mL with an uncertainty of +0.006 mL. The student then uses the calibrated 25 mL pipet to deliver a total of 124.975 mL of solution. What is the uncertainty in the delivered 124.975 mL? 0.375 mL Incorrect How does the uncertainty in the delivered volume using the calibrated pipet compare to the uncertainty in the delivered volume using the uncalibrated pipet? O The uncertainty in the delivered volume is the same for the calibrated and uncalibrated pipet. O The uncertainty in the delivered volume using the calibrated pipet is greater than the uncertainty in the delivered volume using the uncalibrated pipet. O The unceainty in the delivered volume using the calibrated pipet is less than the uncertainty in the delivered volume using the uncalibrated pipet. étv AA A O hulu MacBook Pro
