Interpretation Introduction

Interpretation:

The density of the gas 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.

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.

Red gold is a gold-copper alloy used to make jewelry. A piece of jewelry made of red gold weighs 9.80 g and has a volume of 0.583 cm³. Gold has a density of 19.3 g/cm³ and copper has a density of 8.96 g/cm³. Calculate the percentage by mass of each metal in the jewelry. Assume the total volume of the jewelry is the sum of the volumes of the two metals it contains. gold: copper: % Pure gold is defined as having 24 carats. When mixed in an alloy, the carats of gold are given as a percentage of this value. For example, a piece of jewelry made with 50% gold has 12 carats. State the purity of this piece of red gold jewelry in carats. purity: carats
