Question

What is molality of pure water

Answer 1

Answer:

Just like there's a real molar concentration for water by itself ( 55.348 M ), there is a real molality for water by itself ( 55.510 m ). ... At 25∘C , the density of water is 0.9970749 g/mL , so that's 0.9970749 kg .

Answer 2

Convert the grams to kilograms by multiplying 500 grams * 1 kilogram / 1000 grams. This equals 0.5 kilograms of water. Molality equals moles per kilogram, so the molality is 0.75 moles sodium hydroxide / 0.5 kilograms water, which equals 1.5 m or moles per kilogram
