The density of a liquid substance is 0.95 g/mL. Three students calculated the density as 0.56 g/mL. Calculate the percent error.

Explanation:

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

From the question we have

actual number = 0.95 g/mL

error = 0.95 - 0.56 = 0.39

We have

We have the final answer as

Hope this helps you

2h2o2--> 2h2o + o2

this reaction is of the spontaneous decomposition of hydrogen peroxide down into water and oxygen.
