A student finds the density of an ice cube to be 0.80g/cm3; it is actually 0.90 g/cm3. What is the percent deviation (percent error) in this calculation?
(1)6 percent
(2)11 percent
(3)13 percent
(4)88 percent
(2)?
To calculate the percent deviation or percent error, you can use the formula:
Percent Deviation = (|experimental value - accepted value| / accepted value) x 100
In this case, the experimental value is 0.80 g/cm³, and the accepted value is 0.90 g/cm³.
So, the calculation would be:
Percent Deviation = (|0.80 - 0.90| / 0.90) x 100
= (0.10 / 0.90) x 100
= 0.1111 x 100
= 11.11 percent
Therefore, the correct answer is (2) 11 percent.
