Question

1. The gas constant R (as in PV=nRT) 8.314m^3●Pa/mol●K. Also R= 8.314 J/mol●K. Therefore m^3●Pa equals 1 J. Using the fundamental SI units (m, kg, and s) demostrate that 1 m^3●Pa indeed equals 1 J.

2. Mercury is traded by the "flask," a unit that has a measure of 34.5 kg. What is the volume of a "flask" of mercury in liters at 25°C.

Answer 1

34.5 kg x 1000 g/kg / 13.546 g/cm^3 = 2547 cm^3 = 2547 mL

(I used 13.546 g/cm^3 as the density of Hg)

●is a funny symbol

Answer 2

*steals the answer*

thanks emily! =D

Oh the answer for the 2nd one is actually 2.547 L. (It's asking it in Liters)

And for your first question, the answer is Pa=N/m^2
