59. ▲ Suppose you have a cylindrical glass tube with a thin capillary opening, and you wish to determine the diameter of the capillary. You can do this experimentally by weighing a piece of the tubing before and after filling a portion of the capillary with mercury. Using the following information, calculate the diameter of the capillary. Mass of tube before adding mercury = 3.263 g Mass of tube after adding mercury = 3.416 g Length of capillary filled with mercury = 16.75 mm Density of mercury = 13.546 g/cm3 Volume of cylindrical capillary filled with mercury = (π)(radius)2(length)

Introduction to chemistry

Chemistry is a branch of science that deals with the analysis of material and the substances that comprise it. It also manages the properties of these substances and their reactions to form new substances. It is basically centered on particles and atoms that make up components and mixtures. These chemical species will in general connect using bonds.
