An aqueous solution of HF (MM=20.01 g/mol) has a density of 0.99 g/mL and molarity of 28.9 M. What is the mole fraction of HF?
Added by Grace S.
Step 1
We know that the density of the solution is 0.99 g/mL, so the mass of 1 L of solution is: mass = density x volume = 0.99 g/mL x 1000 mL = 990 g To find the mass of HF in 1 L of solution, we need to multiply the volume of the solution by the molarity of HF and Show more…
