If 0.45 moles of nacl was dissolved in enough water to make 300.0ml of solutions, what is the molarity?

Molarity = Moles / Liters! So in this instance, if you have 0.45 moles of NaCl, and we convert 300.0 mL to 0.3 L, we would plug in M = 0.45/0.3. The answer would be 1.5 M NaCl!

Sorry i dont understand the question can you rephase it?

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.
