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 %

the electron configuration that you gave me has 16 electrons ergo it has 16 protons ergo it is the element sulfur.
