Mary's friend gave her a pendant in the same shape of a rectangular prism for her birthday since she is a science major in college she is interested to know if the pendant is gold she can quickly see if the pendant Is Not Gold if it floats in water. The density of water is 1 g/cm³. If a substances density is less than the density of water it will float if a substance density is greater than the density of water it will sink. The density is gold is 19.3 g/cm³. If Mary's pendant sinks it may or may not be gold but if it floats it is definitely not gold given the mass and dimensions of Mary's pendant predict whether it will float or sink then choose the best answer. Mass=1g length=2cm width=1.5 height=0.5.
A•the density of the pendant is greater than the density of gold therefore the pendant sinks but it might not be gold.
B•the density of the pendant is greater than water therefore the pendant sinks but it might not be gold.
C•the density of the pendant is greater than water therefore the pendent sinks and is gold.
D•when the density of the pendant is less than water therefore the pendent floats and Is not Gold.
