A chemist vaporized a liquid compound and determined its density. If the density of the vapor at 90.0 °C and 753 mmHg is 1.185 g/L, what is the molecular weight of the compound? Given that R = 0.0821 L'atm/(mol·K). %3D O 35.7 amu. O 47.7 amu. O 41.7 amu. O 38.7 amu. 44.7 amu. A sample of nitrogen gas is placed into a container at 200 K. If the temperature of the container is reduced by 150 K and the measured pressure decreases by 50%, how does the volume of the gas change? The volume increases by 50%. The volume increases by more than 50%. The volume decreases by 50%. The volume increases by less than 50%. The volume doesn't change. A chemist vaporized a liquid compound and determined its density.
