The measured value is the value you get when you do the experiment, it is also called an experimental value. the accepted value is the value that is accepted by scientists (it usually comes up when you Google the value of something).

These value are used to calculate percent error.

% error = | Accepted value - Measured Value | / Accepted value × 100

A piece of aluminum has a volume of 12 cm3and a mass of 32 g. What is its density? Do not forget the units.
Contact [7]

Answer:

<h3>The answer is 2.67 g/cm³</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass of metal = 32 g

volume = 12 cm³

The density is

density =  \frac{32}{12}  =  \frac{8}{3}  \\  = 2.6666666...

We have the final answer as

<h3>2.67 g/cm³</h3>

Hope this helps you
