Chapter 1, Problem 1.93QP
Interpretation Introduction

Interpretation: The mass percent of gold in the given mixture has to be calculated using the given data.

Concept Introduction:

Volume is the ratio of mass to density and its SI unit is m3.

Volume=MassDensity

The density of gold metal is 19.3 g/cm3, while that for silver is 10.5 g/cm3. Suppose you had the same size bar of each metal, with the dimensions 2.00 in x 10.0 cm x 760 mm. Volume of a cube is height x length x width. Which bar would have the greatest mass? Which bar contains the greater number of atoms? If the two bars were melted and mixed together to form an alloy (or mixture) what would be the total mass?
Assuming that the copper and lead are pure, determine the relative amounts of each kind of BB. The density of copper is 8.96 g/cm ^ 3 . The density of lead is 11.4 g/cm ^ 3
The density of aluminum is 2.70g/cm^3. For a block of 275g of aluminum calculate the density in liters and calculate the number of atoms.
