Question

1. a student takes an object with an accepted mass of 200.00 grams and masses it on his own balance. he records the mass of the object as 196.5 g. what is his percent error?

Explanation:

Step1: Recall percent - error formula

Percent error=$\frac{\vert\text{Experimental value}-\text{Accepted value}\vert}{\text{Accepted value}}\times100\%$

Step2: Identify values

The experimental value of the mass of the object is $196.5$ g and the accepted value is $200.00$ g.

Step3: Calculate the difference

$\vert196.5 - 200.00\vert=\vert- 3.5\vert = 3.5$

Step4: Calculate percent - error

Percent error=$\frac{3.5}{200.00}\times100\%=\frac{350}{200.00}\% = 1.75\%$

Answer:

$1.75\%$
