The "correct" mass of the cylinder had been previously determined to be 27.20 grams. what was the percent error on his first weighing if bart found the mass to be 25.01 g. show your work.

Percent error =  - 8.1 %

Explanation:

Given data:

Actual mass = 27.20 g

Theoretical mass = 25.01 g

Percent error = ?

Solution:

Formula:

Percent error = theoretical value- actual value/ actual value × 100

Now we will put the values in formula.

Percent error =   25.01 - 27.2 / 27.2 × 100

Percent error = -2.19 / 27.2 × 100

Percent error = -0.081  × 100

Percent error =  - 8.1 %

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
