I suppose this is more of a math question, but it's a bonus question in my chemistry upgrade class. 1. The problem statement, all variables and given/known data Prove the relationship 760mmHg=101.35kPa mathematically, by using conversion factors. 2. Relevant equations 1 Pa=1 kgm/s2 (No it doesn't?...) density of Hg=13.6g/cm3 acceleration due to gravity=9.8m/s2 3. The attempt at a solution I'll be honest, my mind is totally blanking on this, I know my math skills should be able to handle this no problem, but it feels like all my math skills have ran away for the summer. I mean yeah I can convert 101.35kPa into an area using gravity I guess, but I'm not sure what that tells me. While telling me how to get the answer would be great, I'd even be happy with a hint at where to get start.
