nsity Why should weighing data or any other measurement data be recorded immediately in your laboratory manual and not on a scrap of paper? 1. 2. An object was carefully weighed five times on a multiple-beam balance. The balance was each time. The masses were: 11.36 g 11.37 g: 11.40 g: 11.38 g and 11.39 g a. Calculate the average value of these measurements. (Please show all work.) average b. Calculate the standard deviation, s.d., of this set of measurements using the range of the data and the sauare root of the number of measurements averaged. (Please show all work.) Calculate the density of a st lid if it has a mass of 8 47 g and a volume of 3.24 cm3 Please show your calculations, with units, below. 3. density-

Explanation / Answer

Ans 1 :

One should always record the weighing data and measurement data in the laboratory manual instead of a scrap of paper because the latter is easy to misplace .

One can accidently throw away the scrap of paper or loose it anywhere. This causes the lost of data as well.

And also when the data is recorded in manual neatly it can be used for the future references as well .
