wonderd Posted July 1, 2009 Share Posted July 1, 2009 (edited) is a scale to the 10th of a gram good enough to weigh chemicals powder or does it have to be 100th of a gram? Edited July 1, 2009 by wonderd Link to comment Share on other sites More sharing options...
Kyrisch Posted July 1, 2009 Share Posted July 1, 2009 It depends on what you're doing with it and how many significant figures you need on the weight. For instance, if you're doing something like dissolving the powder chemical in some solvent, but you only have the volume of the solvent to one significant figure, it's not necessary to measure to the hundredth of a gram (3 sig-figs) because any calculations will only be significant to one digit.

John Cuthber Posted July 1, 2009 Share Posted July 1, 2009 It also depends on how much stuff you are weighing. A kilogram measured to 0.1 of a gram is pretty good accuracy Link to comment Share on other sites More sharing options...
