Question

If a 100.-g sample of platinum metal has a volume of 4.665 cm3, what is the density of platinum in

g/cm
b
C
d
21.4 g/cm
none of these
466 g/cm3
0.0467 g/cm
2.14 g/cm
e

Answer 1

The answer is

21.4 g/cm³

Step-by-step explanation:

The density of a substance can be found by using the formula

`density = (mass)/(volume) \\`

From the question

mass of platinum = 100 g

volume = 4.665 cm³

The density of the metal is

`density = (100)/(4.665) \\ \approx21.436227224...`

We have the final answer as

21.4 g/cm³

Hope this helps you
