#m_'solute' = (3.62 * '1500.0 g')/100 = color(green)('54. Step 4: Determine the Volume of Bleach Required or Mass of Granular Chlorine Required by reading across the row for the Desired Concentration of Chlorine. #'% m/m' = m_'solute'/m_'solution' xx 100# This solution dilution calculator tool calculates the volume of stock concentrate to add to achieve a specified volume and concentration using the formula. #1500.0 color(red)(cancel(color(black)('g solution'))) * '3.62 g NaOCl'/(100color(red)(cancel(color(black)('g solution')))) = color(green)('54.3 g NaOCl')#ДЄlternatively, you can use the equation for percent concentration by mass to find the mass of the solute In your case, the mass of the solution is said to be equal to #'1500.0 g'#. Step-by-Step Instructions 1 Create an opening 2 Determine amount of bleach 3 Right type of chlorine bleach 4 Dilute the bleach 5 Pour the diluted bleach 6. Looking at the above definition, that should tell you that every #'100 g'# of solution will contain #'3.62 g'# of sodium hypochlorite, your solute. You are told that your bleach solution has a #'3.62%# percent concentration by mass. Use a clean 25-mL volumetric pipet to deliver 25.00 mL of bleach solution into a clean 250-mL volumetric flask. This step can be performed with a partner and the diluted bleach shared. Using bleach with a concentration of: Water 2.75 5.25-6. Perform a 10-fold quantitative dilution of bleach. #color(blue)('% m/m' = 'mass of solute'/'mass of solution' xx 100)# Disinfecting Solutions For use on diaper change tables, hand washing sinks, bathrooms (including toilet bowls, toilet seats, training rings, soap dispensers, potty chairs), door and cabinet handles, etc. The key to this problem lies with the definition of percent concentration by mass, #'m/m %'#.ДЄs you know, percent concentration by mass is defined as the ratio between the mass of the solute and the total mass of the solution, multiplied by #100#.
