Answer to Question #184777 in General Chemistry for Mary

Question

1. You find a piece of metal in an old chest in your attic . It looks like gold, but it could be a cheap metal made to look like gold. You remember from your science class that gold has a high density of close to 20 g/em, and that gold is much denser than most other metals. You decide to carry out an experiment to measure the density of the of metal that you foundthe mass of the metal is found to be 687 g and its volume is 54 cm'. Based on these measurements , is it likely that the metal you found is gold ?

Answer 1

$Density = \frac{mass}{volume}$

$Density = \frac{687}{54}=12.72g/cm$

Hence the metal is not a gold
