How was Avogadro’s number determined? Jessica Kim 12D Starting from 200 years ago‚ scientists tried to figure out the basic ideas of chemistry. One of them they put lots of effort in was to find out the mass of the smallest particle‚ mole. Measuring the mass was a primary difficulty at that time since one mole of a substance was unable to weigh without using developed technology. Even though‚ it was clear that everything was made out of a small unit‚ there was no evidence that could determine

The second voltage can be reverse determines by: The difference V1 V2 gives a proportional voltage: and the sum of the voltages is a constant : This constant gives the LVDT great stability of the angular information‚ independence of the input voltage or frequency‚ or temperature‚ and enables it to also detect a malfunction. Putting the above mathematical equations in some theoretical form

the same length at two different angles and discovered that the mean time for each was significantly different. For task 3‚ I used dimensional analysis to determine the powers in the model equation and to get the dimensionless proportionality constant k from the data we collected in DataStudio. By using dimensional analysis‚ I was able to arrive at the math model to be able to dissect the equations from my graphs. Below is the work for my dimensional analysis: M0S1 = (kmx)/(s2x)*my M0S1

old. Since next year Kevin will be 2 times as old as Margaret‚ you can write the equation . Solve this equation by simplifying it‚ step by step: (after brackets opening at the right side) (after moving variable terms to the right and constant terms to the left) (after combining like terms) Thus‚ you got that Kevin’s present age is years. Check. If Kevin’s present age is 7 years‚ then Margaret is years old now. Next year Margaret will be 4 years old‚ while Kevin will

Objective: To determine the concentration and equilibrium constant for a reaction of colored product using absorption spectroscopy‚ to create a calibration curve for determining equilibrium concentrations by applying Beer’s law and to force the completion of a reaction by applying Le Châtelier’s principle. Procedure: A diluted solution was made from the stock of 0.0025 M Fe(NO3)3 by diluting 4.0 mL to exactly 100.00 mL‚ using serological pipet and volumetric flask. The concentration of the diluted
