A1.0 mole sample of krypton gas has a mass of?

Kr, with atomic number 36, has a molar mass of 83.798 g/mol. That is by meaning the mass of Kr gas atoms for every 1 mol of krypton gas atoms. So: 1 mol x 83.798 g Kr / mol = 83.798 g Kr. is the mass of 1 mole sample which is also the molar mass of the element.

Ans. : frostbite is when exposure to cold temperatures causes freezing to the skin or other tissues. it most commonly affects the hands, feet, and face. the longer areas are exposed to cold, typically the worse the frostbite. the water temperature used for rewarming a frostbitten part should be : (102 -105) f degrees.
