analytical balance Flashcards
What is mass? How is it determined?
The amount of matter in object;
is determined by using a balance
How are mass and volume of a substance related?
By density D= m/v
What is the percentage error formula?
% error = average - theoretical mass / theoretical mass
What is theoretical mass?
The mass of the standard
What is the range?
The difference of the largest and smallest value
What is the specific volume?
The volume occupied by one gram of water corrected for buoyancy of air
What is percentage error?
Allows you to access the accuracy or closeness to true value
What is the difference between data and results?
The data is the measurements and information used before the results and the results are the calculations used from the data
What does the sign of the error tell you about the error?
If the error is positive, it means the experimental value is larger than the expected value. If the error is negative, it means the experimental value is less than the expected value
Why is it important to not touch the standard mass?
The weight of the fingerprints would increase the mass making the mass inaccurate
