Question

if mole fraction of Naoh in an aqueous solution of Naoh is 0.2 then molality of solution is​

Answer 1

Answer:

. The formula for molality is m = moles of solute / kilograms of solvent. In problem solving involving molality, we sometimes need to use additional formulas to get to the final answer. One formula we need to be aware of is the formula for density, which is d = m / v, where d is density, m is mass and v is volume.
