Homework Statement [/B] The scalar triple product computes the magnitude of the moment of a force vector about a specified line. It is M = ( r×F ) ⋅n , where is the position vector from the line to the point of application of the force and is a unit vector in the direction of the line. Prompt...

1 hydrogen has 1 proton but in sulphuric there are 2 hydrogen

sulphuric has 2 protons. so ph =-log(0.0004) =-(log4-4) =-(0.6021-4) =3.3979
