Answer:
21.4666666667 g/cm^3
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.
