[yuvlevental]

A rock hound finds a solid rock that contains only quartz and gold. The rock has a mass of 12.08 kg and a volume of 3.909×10-3 m^3. What is the mass of the gold contained in the rock?

Density of gold: 19300 kg/m^3
Density of quarts: 2660 kg/m^3

This appears to be a homework problem that you want us to answer for you. We are not here to do your homework. At best we expect to see how far you've gotten or what you believe may be the right way to solve it or tell us you have no clue on how to approach it. Only then will we help you obtain an answer to your question. This is forum policy and I, personaly, will not step beyond that policy out of respect to the forum owner and his assitants. The specific policy that is being ignored here (not by intention I'm sure) is this part You MUST show that you have attempted to answer your question in order to receive help.

It states

Homework Help:
On posting questions: Any and all high school and undergraduate homework assignments or textbook style exercises for which you are seeking assistance are to be posted in the appropriate forum in our Homework & Coursework Questions area. This should be done whether or not the problem is part of one's coursework. The reason for this is that the scientific and mathematical sections of Physics Forums are to be reserved for discussions and not academic assistance. Since graduate level assignments are meant to be more thought provoking (and hence more worthy of discussion), graduate level questions will be allowed in the relevant part of the main section of PF, provided that the graduate student attempts the problem and shows his work. NOTE: You MUST show that you have attempted to answer your question in order to receive help. You MUST make use of the homework template, which automatically appears when a new topic is created in the homework help forums.

We do not support cheating in any form: Do not ask for solution manuals, answers to exams, or instructor's manuals.

On helping with questions: Any and all assistance given to homework assignments or textbook style exercises should be given only after the questioner has shown some effort in solving the problem. If no attempt is made then the questioner should be asked to provide one before any assistance is given. Under no circumstances should complete solutions be provided to a questioner, whether or not an attempt has been made.

The Homework & Coursework Questions area is located at

When you've shown us your attempts to try to solve this problem only then can we assist.

Best regards
