Abstract
In the following article will be released some of the instruments of the laboratory, for the handling of chemicals. There is a wide variety of materials from the thermometer that is used to find the temperature to the graduated cylinder that is used to find the volumes of a chemical, thus demonstrating its use and utility, with the aim of differentiating between precision and accuracy, through of the equations which the precision tells us what is the repeatability or reproducibility of the measurement and the accuracy indicates the proximity of the results that there are of the measurements obtained with respect to the true value that is being given based on these obtained data was determined the absolute error that is the difference between the approximate value and the real value in order to see how scattered the data are, in the same way the relative value was found to determine the precision of the measurement. This provided the error with respect to the exact value of what was measured.
