A volatile liquid was vaporized in a 250 mL flask placed in a boiling liquid. After cooling to room temperature, the mass of the liquid remaining was 0.950 g. If the temperature of the boiling point was 152 °C, and the barometric pressure was 744 torr, what is the molecular weight of the substance?

Silver tarnishes as silver metal reacts with hydrogen sulfide, h2s, in the air. in this reaction, dark silver sulfide, au2s, covers the surface of silver. when silver is polished, this coating of silver sulfide can be removed from the surface. this makes the silver shiny again. enter the coefficients that balance the tarnishing reaction equation. (type 1 for no coefficient.)

Which of the following best supports the concept that genetic information is passed on to offspring from both of their parents, not just one?
