Question

If the density of some lake water is 1.25 g ml and contains 92 g of Na ions per kg of water calculate the molality of Na ions in the Lake
​

Answer 1

Answer:

Mass of sodium ions = 92 gMolar mass of sodium ions = 23 g/molNumber of moles of sodium ions = 23g/mol92g = 4Mass of water =1 kgMolality = Mass of water

Answer 2

Explanation:

Hope the solution helps you
