    MV1 - 2MV2 = 0 V1 = 2V2...... ( i) Now! ( 1/2 mV1^2) / (1/2 (2m)V2^2) You replace i. Then get 2/1

    Okay! So if I get the percentage uncertainty of a measured value as 14% and my constants have %uncertainty of 25% then my value is proportional within the limits right?? I’ve been doing this! Just got confused... Just out of curiousity, I wanted to know what you do at your side of the globe! Lol!

    Im sure you calculated the Mr for i. 1 gram of the sample was taken so you divide the mass by Mr. You then get the number of moles. Which will be equal to one of the answers on the table for AgCl. Then you calculate the other values of n simply by looking at the ratios. (These were just the...
