How can one determine the molar mass of a substance by considering its density, pressure, and temperature?
To determine the molar mass of a substance using density, pressure, and temperature, one can use the ideal gas law equation, PV nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature. By rearranging the equation to solve for molar mass (M), M (mRT)/(PV), where m is the mass of the substance, one can calculate the molar mass by plugging in the given values for density, pressure, and temperature.
If the pressure of gaseous chloroform in a flask is 195 mm Hg at 25C and its density is 1.25 gL what is the molar mass of chloroform?
Using the ideal gas law, we can determine that the molar mass of chloroform is approximately 119 g/mol. Given the pressure, temperature, and density of chloroform, you can calculate the molar mass using the formula: (pressure x molar mass) / (gas constant x temperature) = density. Solving for molar mass gives approximately 119 g/mol.

What is the relationship between molar mass and density in a substance?
The relationship between molar mass and density in a substance is that as the molar mass of a substance increases, its density also tends to increase. This is because a higher molar mass means there are more particles packed into a given volume, leading to a higher density.
Calculate the average molar mass of dry air if it has a density of 1.17 gL at 21oC and 740.0 torr?
To calculate the average molar mass of dry air, we can use the ideal gas law. Given that the density of dry air is 1.17 g/L at 21°C and 740.0 torr, we can calculate the molar mass using the formula: Molar mass = (dRT)/(P), where d is the density, R is the ideal gas constant, T is the temperature in Kelvin, and P is the pressure. Substituting the values and units, we can find the average molar mass of dry air.
