Question

I fill a graduated cylinder with 124.6 mL of water. When I transfer this water to a 400 mL beaker, it comes up to

"146.9. ml" on the beaker's scale.
The percent error in this beaker is:
a. 15.2 percent
b. 0.848 percent
c. 17.9 percent
d. 22.3 percent
e. 1.18 percent

Answer 1

To calculate the percent error, we need to determine the difference between the actual value and the experimental value. The actual volume of water that was transferred to the beaker is 124.6 mL. The experimental value, as measured by the beaker, is 146.9 mL. To find the difference, we can subtract the actual value from the experimental value:

146.9 mL - 124.6 mL = 22.3 mL

Then, we can calculate the percent error using the following formula:

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

Substituting the values we calculated earlier, we get:

Percent Error = (|146.9 mL - 124.6 mL| / 124.6 mL) x 100%

Percent Error = (22.3 mL / 124.6 mL) x 100%

Percent Error = 17.9%

Therefore, the percent error in this beaker is 17.9 percent.
