Interpretation Introduction

Interpretation: The unknown compound has to be identified.

Concept Introduction:

Density: Is a characteristic property of a substance. The density of a substance is the relationship between the mass of the substance and how much space it takes up (volume).

  Density = MassVolume

Explanation

Reason for true statements

The density of the compound is calculated as,

  Calculate the volume of unknown compound:_Volume of marble  = final volume of water - initial volume of water                                = 21 ml - 7ml = 14 mlCalculate the density of unknown compound:_Given: mass =37
