Question

a student calculates experimentally the value of density of an iron as 4.4 gcm³. if the actual density of an iron is 7.6 gcm³, calculate the percentage error in experiment

Answer 1

The percentage error in the experiment is 42.1%.

Step-by-step explanation:

The percentage error in the experiment can be calculated using the formula:

Percentage Error = (Actual Value - Experimental Value) / Actual Value x 100%

Using the given values:

Actual Density of Iron = 7.6 g/cm³

Experimental Density of Iron = 4.4 g/cm³

Percentage Error = (7.6 - 4.4) / 7.6 x 100% = 3.2 / 7.6 x 100% = 42.1%

Answer 2

hola!

Percentage Error is a measurement of the discrepancy between an observed and a true, or accepted value.

According to Question,

% error =
`(7.4 - 7.6)/(7.6)` × 100

= 2.631 % = 2.7 % (approximately.)

hope it helps!
