Welcome | my.REDLANDScc <Homework 7C - Attempt 1 + Gas Density and Molar Mass which can be rearranged as X 08 I Content Pressure and temperature affect the amount of space between gas molecules, which affects the volume and, therefore, the density of the gas since mass density = volume The molar mass of a substance, however, is a constant and can be used to identify an unknown gas sample. Molar mass is found by dividing the mass of a sample (in grams) by the number of moles in that sample. The number of moles of gas can be calculated using the ideal gas law PV = nRT Type here to search https://session.masteringchemistry.com/myct/itemView?assignment ProblemID=191597257&attemptNo=1 MasteringChemistry: Homewor X n = PV RT Given the number of moles of a gas and its molar mass, you can calculate the mass of the gas. Since density is equal to the ratio of the mass and volume, you can then divide by the volume to find density. Alternatively, you can use the ratio n/V from the ideal gas equation where is the number of moles and V is the volume, and convert from moles per unit volume to grams per unit volume using molar mass 6: 20 MasteringChemistry: Homewor X + Part A Calculate the density of oxygen, O₂, under each of the following conditions: • STP . 1.00 atm and 35.0 °C Express your answers numerically in grams per liter to three significant figures.
