Question

While prospecting in the woods, you find a solid gold nugget. You don’t have a scale to weigh it, but you remember that the density of gold is 19.2 g/mL and you have a graduated cylinder. When you put water in the cylinder and then place the nugget into it, the water level rises 15 mL. What is the mass of the nugget?

Answer 1

mass = density x volume

 

density = 19.2 g/mL

volume = 15 ml

 

Plug in the numbers and get mass in grams.
