There are 0.15 ml of the water contains 150 mg of Pb .
Calculation ,
Formula used :
density = mass / volume ( i )
Given mass of the Pb in milligram ( mg ) = 150 mg
Given mass of the Pb in gram ( g ) = 150 × = 0.15 gram
Given density = 1.0 g/ml
We have to find volume of water in milliliter ( ml ) .
Putting the value of mass of the Pb , lead and density in equation ( i ) we get the volume of water in milliliter ( ml ) .
density = mass / volume
1.0 g/ml = 0.15 gram / volume
volume = 0.15 gram / 1.0 g/ml = 0.15 ml
