Astudent is asked to convert measurements from liters to milliliters and from milliliters to liters. his answers are shown in bold in the choices shown below. on which choice did he make a mistake? 0.523 l = 523 ml 0.0607 l = 60.7 ml 7.2 l = 72,000 ml 23.6 l = 23,600 ml

Answer is "7.2 L = 72,000 mL".

Explanation :

1 L = 1000 mL

- To convert liters into milliliters you have to multiply the value by 1000.
  Example : Q :Convert 0.523 L into mL
                 
                    A : 0.523 L = 0.523 x 1000 mL = 523 mL

- To convert milliliters into liters you have to divide the value by 1000.  
  Example : Q :Convert 523 mL into L
                 
                    A : 523 mL =  ( 523 / 1000 )L =  0.523 L    

Hence, the correct conversion for the 7.2 L should be
                 7.2 x 1000 mL = 7,200 mL
