I'm confused about the volume of liquid [ml] part of the table is that the amount in the burette ex) if you take 0.50 ml out then do you write 4.50 or do you write 0.50
For the density of water, the units should be g/ml. If you recall from your mathematics course, slope is rise over run. The mass should be on the y-axis [rise], while the volume should be on the x-axis [run]. Please create a line of best fit, do not simply connect all the points.
You refreshed your page when calculating initial burette and final burette and I did the same because I was following along, was I supposed to refresh when calculating the initial/final burette? Also, ik that my initial burette for trial 1 is supposed to be 0.00 ml but for the final burette trial 1, is the reading supposed to be what I got in total mass for Trial 1? or just 0.50 ml as you said in the video and that's what I put because of refreshing the page.
The initial reading is 0.00 ml. You then add about 0.50 ml. The initial reading for trial 2 is the final reading for trial 1 (again 0.50 ml). You then add another 0.50 ml, the final reading for trial 2 is now 1.00 ml. This reading (1.00 ml) is now the initial reading for trail 3... this continue. The final row is the total volume in the beaker, it is NOT the difference between the two previously lines that would be 0.50 ml each time. If you added 0.50 ml each time the final row would be the final reading from the corresponding trail minus the initial reading from trial one. Example: The initial reading from trial 1 is 0.00 ml. The final reading for trial 1 is 0.50 ml. For the final row: 0.50 - 0.00 = 0.50 ml. The initial reading from trial 1 is 0.00ml (as always.) the final reading from trial 2 is 1.00 ml. For the final row: 1.00 ml - 0.00 ml = 1.00 ml (the volume in the beaker.)
You can put the final burette value as the final volume [IF] the initial reading for your first trial was exactly 0.00 ml. Otherwise the final burette reading would not be the volume of water in the beaker.@@ayeshaarslan1381

You write 0.50 ml. Burettes measure what is dispensed.
Do we draw the line connecting the points on the density graph? And should the x-axis be mass, grams and y-axis be volume, ml?
For the density of water, the units should be g/ml. If you recall from your mathematics course, slope is rise over run. The mass should be on the y-axis [rise], while the volume should be on the x-axis [run]. Please create a line of best fit, do not simply connect all the points.

What if i put the same values as my final burette in the volume row, would that work? Also, thank uu for the detailed clarification!!

Is all data collection expected to be written in ink?
The date can be written with pen or pencil. Either is fine.
Do you see the colorful texts on page 3 table 1 or do I have eye problem? :(
Without the owner password, you do not have the power to write on the document?
I don't know what you mean? What document?
I can’t edit or write on the 6 pages you are showing here through iPad @@michaelvitarelli1589
Good
