_____________________________________________

Solution 3 Is The Most Concentrated

S1:

M = m/v

= 100ml ÷ 2 spoons × 100%

= - 5,000 μg/ppb³

= 50% Diluted

S2:

M = m/v

= 200ml ÷ 5 spoons × 100%

= - 4,000 μg/ppb³

= 40% Diluted

S3:

M = m/v

= 300ml ÷ 6 spoons × 100%

= - 5,000 μg/ppb³

= 50% Diluted

S4:

M = m/v

= 600ml ÷ 8 spoons × 100%

= - 75,000 μg/ppb³

= 75% Diluted
