Answer to Question #122885 in General Chemistry for emily

Question

if i have a bottle of bleach that is 5% sodium hypochlorite, what is the concentration in mol/L and how would i figure it out?

Answer 1

Explanation:

This requires an assumption that there is 5g solute and 95g solvent in 100g solution. Going from this:

So we have :

Molecular weight of sodium hypochlorite=74.44g/mol

Mass of sodium hypchlorite as per the question is 5g

Molarity=5/74.44=0.067mol/L

=0.067M.
