Solved: In 1849 a gold prospector in California collected
Chapter 1, Problem 93P(choose chapter or problem)
In 1849 a gold prospector in California collected a bag of gold nuggets plus sand. Given that the density of gold and sand are \(19.3\mathrm{\ g}/\mathrm{cm}^3\) and \(2.95\ \mathrm{g}/\mathrm{cm}^3\) respectively, and that the density of the mixture is \(4.17\mathrm{\ g}/\mathrm{cm}^3\). calculate the percent by mass of gold in the mixture.

QUESTION:
In 1849 a gold prospector in California collected a bag of gold nuggets plus sand. Given that the density of gold and sand are \(19.3\mathrm{\ g}/\mathrm{cm}^3\) and \(2.95\ \mathrm{g}/\mathrm{cm}^3\) respectively, and that the density of the mixture is \(4.17\mathrm{\ g}/\mathrm{cm}^3\). calculate the percent by mass of gold in the mixture.
ANSWER:
Step 1 of 4
Here, we are going to calculate the percent gold in mass from the mixture.
Given that,
Density of Gold () = 19.3 g/
Density of sand ()= 2.95 g/
Density of the mixture () = 4.17 g/
We know that,
Density is defined as the mass per unit volume.
