J-tube Calculation

APCHEM-M0JIVG

Boyle's Law can be used to calculate atmospheric pressure with a simple glass J-shaped tube. An experiment is done with two different diameter tubes in a laboratory. The smaller diameter tube resulted in a measured atmospheric pressure of 746 mmHg. The second tube was twice the diameter of the first tube, but no additional mercury was added.

Which of the following would be the expected measured value from the second J-tube?

A

373 mmHg

B

559 mmHg

C

746 mmHg

D

1492 mmHg
