Question

Convert 10% w/W into %w/V ,if the density of the solution is 1.05 g mL-1.​

Answer 1

Answer:

if the solvent is 10% by mass then it means the mass of sloute =10g

the mass of sloution =100g

density =mass/volume

density of solution =1.05g ml-1

volume of solution = density ×mass

=1.05×100

=105ml

%w/v= (mass of solute×100)/volume of solution

= (10×100)/105

=9.52%
