Question

Problems from Chemistry:
a)Hurricane Katrina, which hit the Louisiana/Mississippi Gulf Coaston August 29, 2005, had the second lowest ever recorded barometricpressure at 920mb. Convert this pressure to units of atmospheres,kilopascals, and inches of Hg. b) Determine the volume (inmL) of 1.0 teaspoon. 1 tablespoon = 3 teaspoon; 1 tablespoon =1/2 fluid ounce.

Explanation / Answer

920 mb *(1bar/1000 mb) *(1e5 Pa/ bar)*(1kPa/1000Pa) = 92.0 kPa 92 kPa *(1000 Pa/1kPa)*(1atm/101325 Pa) = 0.907 atm 92.kPa *(1000 Pa/1kPa)*(760 mmHg/101325 Pa) *(100 cm/1000cm)*(1in/2.54 cm) = 27.2 inHg b) 1.0 teaspoon *(1 tablespoon/3 teaspoon)*(0.5 fluidounce/1tablespoon) *(29.5735295625 mL/fluid ounce) = 4.92 mL EDIT: Links removed for Cramster's policy
