Using "dimensional analysis" show that 1 L kPa = 1 J.
Hints : P= F/A; 1 Pa = 1 N/m^2; energy = F x d© BrainMass Inc. brainmass.com October 16, 2018, 4:05 pm ad1c9bdddf
The best way to solve this problem is by dividing it to 2 parts and taking each side of the equation alone.
Lets start with 1L Kpa.
We know that Pa=1N/m^2 we also know that a L is also a dm^3 which means we can say that 1L ...
Demonstrating that the right side of the equation and the left side of the equation are equal. 200 words.
Molecular Formula of a Gas
A gaseous hydrogen and carbon containing compound is decomposed and found to contain 85.63%C and 14.37%H by mass. The mass of 258 mL of the gas, measured at STP, was found to be 0.646 grams. What is the molecular formula of the compound?View Full Posting Details
