QUESTION:
Explain the difference between random error and systematic error.
ANSWER:Solution 31 E: (a) Here, we have to calculate the density of the liquid Given in the question Volume of the sample she measured = 45.0 mL Mass of the sample she measured = 38.5 g We know the relationship between Density and volume with mass is given below Density defines the mass per unit volume. By definition Density = Mass/ Volume = (38.5g/ 45.0 mL) = 0.8555 g/mL 0.866 g/mL The calculated density of the liquid sample is found = 0.866 g/mL which is equal to the density of toluene (0866 g/mL). Therefore, the liquid sample would b toluene. (b) We have to calculate here, the vol
