Answer to Question #241034 in General Chemistry for Aii

Question

A sample of platinum has a mass of 102g. When the sample is placed in a graduated cylinder containing 25.9mL of water, the water level rises to 30.3mL. What is the density of the platinum

Answer 1

Volume of platinum $=30.3-25.9=4.4ml$

$Density =\frac{Mass}{Volume}$

$Density =\frac{102}{4.4}=23.18g/cm^3$
