In one of the routine analyses, Dr Entropy found that the concentration of phosphate had increased from 0.0090 mg/L to 0.220 mg/L.
In one of the routine analyses, Dr Entropy found that the concentration of phosphate had increased from 0.0090 mg/L to 0.220 mg/L. This will require a lengthy investigation and detailed report into the causes. Being the master of disorder, he considers an act of serious scientific misconduct - diluting the sample to reduce phosphate concentration to the maximum allowable level of 0.100 mg/L, and hoping that no-one notices.
If the volume of the original sample with concentration 0.220 mg/L is 10.0 mL, what should be the final volume of solution in order to dilute it to 0.100 mg/L?
Can you assist in showing how to work this out?
