Name (please print): Fall 2022 Basic Laboratory Operations Post Lab Questions 1.) Suppose you're attempting to measure the density of a liquid that is highly volatile (it evaporates quickly). If you first measure the mass and then several minutes later you measure the volume of the liquid will the measured density be higher than the true value, lower than the true value, or the true density of the liquid. [It helps to understand this problem with the density equation.] 2.) Suppose you're attempting to measure the density of a liquid that is highly volatile (it evaporates quickly).

Task 3 Radioactive decay is the process of transforming nucleus from unstable state to more stable state. The rate of radioactive decay depends on the specifications of the substance. Depending on that, we can define the half-life as the amount of time needed to convert half of the substance from the unstable radioactive state to the stable state. If you know that the rate of decay for a certain substance is proportional to the amount of the current substance x(t). Formulate a differential equation to express the previous (i) system. (ii) Solve this first order differential equation. (ii) If you know that for a certain substance (carboon-14), 5730 years are needed to convert half of the substance, find the value of the proportional constant.
