Interpretation Introduction

Interpretation:

The density of the empty container should be calculated with giving the appropriate significant figure.

Concept Introduction:

Density: The density of the substance is calculated using the formula:

density = massvolume

For the given set of calculations the significant figures and their correct measurement has to be given.

Concept introduction:

Significant figures: The digits having a meaning in a given number are called as significant figures.

Significant figures –calculation rules

Significant figure is a non-zero number (4443.2 has five significant figures)

Zeros placement in between non-zero number are significant figures (40005 has five significant figures).

Zeros before the non-zero number are not significant number (0.00040005 has five significant figures).

Zeros after the non-zero number are significant in case of that number contains decimal point (4.5000 has five significant figures).

Zeros after the non-zero number may or may not be a significant figure in case of that number does not have a decimal point (500 may have 1, 2 or 3 significant figures). In this cases use scientific notation to avoid ambiguity.
