    Chemical Eng: How do I get value M from 2 unknown variables.

    Hi again! I think you both have helped me out enough now. I greatly appreciate it. What I've did is T2 = [M.(rms)^2] \ 3R] / T1 = [M.(rms)^2] \ 3R] (T1+24)/T1 = ratio Solve for T1 Then use that figure to solve for T2. I'm hoping this is correct. I hope you both will be able to help me...

    Chemical Eng: How do I get value M from 2 unknown variables.

    Hi DrClaude. I don't know if I have did this correctly, but my logic is this: I have rearranged (3RT1/M)^0.5 to become (rms)^2 = 3RT/M What I have now done is this: (rms)^2 = 3RT2/M T2 = [M.(rms)^2] \ 3R...

    Chemical Eng: How do I get value M from 2 unknown variables.

    Homework Statement At T1 the root mean square speed (rms) of compound P is 485.2 m s-1 and at T2 the rms speed is 504.1 m s-1. Using this data and the fact that T2 – T1 = 24.0 °C, determine the molar mass of P in g mol-1. Homework Equations From problem statement you have: (3·R·T1/M)1/2 =...

    Thinking of starting a course in Electrical Engineering?

    I appreciate your response. You highlighted in particular that the transition into the workforce as an E.E. can be intimidating and I agree that the work culture can vary from place to place. These questions are more fundamental for me than, say, what E.E's focus on (because the internet can...

    Thinking of starting a course in Electrical Engineering?

    Dear readers, Firstly I would like to say that I'm a new member to the Physics Forum and I hope to meet many people who share my passion for science and, at present, engineering (because let's face it, science/engineering is awesome!). As a recent chemistry graduate at the University of...

    Dear Physics Forum: Calculus problem (Physical Chemistry)

    Thank you very much mate. I thought that was correct and as usual I've over complicated it more than required. Appreciated fully. L.

    Dear Physics Forum: Calculus problem (Physical Chemistry)

    Homework Statement In the electrochemists technique of cyclic voltammetry, the peak current, I, is a simple function of the scan rate, v, according to the Randles-Sevcik equation: Homework Equations I = 0.4463nFAc(nF / RT)^1/2 D^1/2 V^1/2 Where n is the number of electrons transferred, F is...
