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 %

water is used to store them because it would keep the radiation from getting out in the open and causing harm to the workers

the dependant variable is spilled water

the independent is the heat
