Chemistry

The concentration of an unknown must be in the range of theknown concentrations. You sometimes must dilute an unknown so thatthe concentration is lower than thehighest concentration measuredfor your standard curve.
a. If you dilute 1mL of an unknown solution with 1 mL of water,the dilutedconcentration would be 1mL in a total of 2mL ofsolution. How would this affect the concentration? What is thedilution factor?
b. One would then have to reverse this process when reportingthe original concentrationof the unknown solution. What factorwould be used to calculate the originalconcentration?

c. If 1mL of unknown solution was diluted to 10mL final volume,what is the dilutionfactor? How would one calculate the originalconcentration?

d. If 2 mL of unknown solution was diluted to 5mL final volume,what is the dilutionfactor? How would one calculate the originalconcentration?
