Question

A nugget of unknown metal with a mass of 280.8 g is added to 150.0 mL of water.

The water level rises to a volume of 177.0 mL. What is the density of the metal?
A) 10.4 g/mL
B) 6.77 g/mL
C) 1.00 g/mL
D) 0.0518 g/mL

Answer 1

the answer is 10.4 because the unknown metal has displaced 27ml of water!

density= mass/volume

so therefore 280.8g/27ml= 10.4g/ml
