Using mass to calculate molecular formula
... If 3.4 g of methane are burnt in excess oxygen, what mass of carbon dioxide is formed. 13.4 g of CH4 is 13.4/16 = 0.837 mol of CH4 Equation shows that 1 mol CH4 produces 1 mol CO2, therefore 0.837 mol CO2, mass 0.837(12+2x16) = 36.8 g are formed. If 0.7 mol of CH4 is reacted with 0.5 mol O2, what is ...

Tue., Feb. 5 - Ion counters and conductivity meters
... We spent the entire class examining ion counters and conductivity meters. A crude and quickly assembled instrument was demonstrated in class. Ion counters measure the concentration of small ion charge carriers in the air (as we will see they can only measure one polarity of charge carrier at a time) ...

Nanofluidic circuitry
Nanofluidic circuitry is a nanotechnology aiming for control of fluids in nanometer scale. Due to the effect of an electrical double layer within the fluid channel, the behavior of nanofluid is observed to be significantly different compared with its microfluidic counterparts. Its typical characteristic dimensions fall within the range of 1–100 nm. At least one dimension of the structure is in nanoscopic scale. Phenomena of fluids in nano-scale structure are discovered to be of different properties in electrochemistry and fluid dynamics.
