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

Silver's chemical symbol is Ag, and it has a 1+ charge. Nitrogen's chemical symbol is N, and it has a 3- charge. For silver and nitrogen to form a compound, their charges must cancel out to zero. Therefore, we would need 3 silver atoms for each nitrogen atom to balance the charges out. The formula for the silver nitride compound would be Ag3N.

An analogy is a comparison between two things
Example: banana is to yellow as red is to apple OR banana:yellow as red:apple
A metaphor is a figure of speech where a word or phrase is applied and it’s not literal.
Example: it’s raining cats and dogs. It’s not really raining literal cats and dogs. It’s just raining really hard.
