When a certain acid and a certain base are mixed together, a reaction occurs that produces a gas as one of the products. The gas has a density of 2.62 g/L at 1.47 atm and 27°C. What is the molar mass and identity of the gas?

The molar mass of the gas can be calculated using the ideal gas law:PV = nRTwhere P is the pressure, V is the volume, n is the number of moles, R is the ideal gas constant, and T is the temperature.We can rearrange this equation to solve for the molar mass:M = (m/V) * RT/Pwhere M is the molar mass, m is the mass of the gas, and V is the volume of the gas.We are given that the density of the gas is 2.62 g/L, which means that the mass of 1 liter of the gas is 2.62 g. We are also given that the pressure is 1.47 atm and the temperature is 27°C, which is 300 K.Substituting these values into the equation, we get:M = (2.62 g/L) * (0.0821 L atm/(mol K)) * (300 K) / (1.47 atm)= 44 g/molTherefore, the molar mass of the gas is 44 g/mol, which corresponds to CO2.
