The daily intake of iron is 18 mg for an adult. This dose dissolved as Fe2+ ions in 1 liter of water makes an 18 ppm Fe2 solution. Convert 18 ppm Fe2 to molarity. Assume the aqueous solution is dilute enough to use the shortcut and the solution density is essentially equal to water (1.0 g/mL). Answer to 2 significant figures with appropriate units.

Harvey kept a balloon with a volume of 348 milliliters at 25.0˚c inside a freezer for a night. when he took it out, its new volume was 322 milliliters, but its pressure was the same. if the final temperature of the balloon is the same as the freezer’s, what is the temperature of the freezer? the temperature of the freezer is kelvins.
