A student measured the mass of some sodium chloride for a lab. the lab called for 6.25 g (the accurate measurement ) , but the student measured 6.00 g instead . what is the percent error for this mass ? Show your work .

The answer is

Explanation:

The percentage error of a certain measurement can be found by using the formula

From the question

actual mass = 6.25 g

error = 6.25 - 6 = 0.25

So we have

We have the final answer as

4 %

Hope this helps you

The problem here is that according to aufbau principle before 3d orbital 4s subshell comes.after filling 3p orbital with electrons you have 4 electrons left, you place two in 4s with opposite spin and the other two in 3d in any of its two orbitals of total five orbitals with the same spin.

It idk haha what are we doing?
