Explanation: The density of a substance can be found by dividing the mass by the volume. d=m/v The mass of the sample is 16.1 grams and the volume is 0.75 cubic centimeters. m= 16.1 g v=0.75 cm^3 Substitute the values into the formula. d=16.1 g / 0.75 cm^3 Divide d= 21.4666666667 g/cm^3
The density of platinum is 21.4666666667 grams per cubic centimeter.
