distinguished French chemist‚ created a relatively simple method for determining the molecular mass of a volatile substance. In this experiment we will use a modified version of his technique to determine the molecular mass of an unknown volatile liquid. The density of a gas is given by the ideal-gas equation as‚ Dgas = m PM = V RT where M is the molecular mass of the gas. Solving for molecular mass‚ we obtain: € M= mRT PV Thus‚ the molecular mass of a gas can be determined by measuring the

Introduction: The purpose of this lab is to apply Mendel’s laws to predict the probability of the occurrence of a single event‚ of two independent events and of certain traits in offspring of parents exhibiting traits. Gregor Mendel was an Austrian monk in 1866‚ who studied how traits were passed using pea plants. From his studies of inheritance‚ he created three laws of inheritance: the law of dominance‚ the law of segregation‚ and the law of independent assortment. He called genes ‘’factors’’

Lab Report Purpose: The purpose of this lab experiment was to learn about the different densities of different kinds of metal. We used pennies made out of different metals to determine this. After we gather the data‚ it’ll be used to determine the metal used. Hypothesis: In the lab‚ I expect that the pennies before 1982 would be heavier than those that are after 1983 because the metal was initially changed because the earlier pennies cost more to make. So I think that since the heavier metal was
