8.1x^4 x 0.2 = 1.62x^4
Step-by-step explanation:
Answer:
The answer is
<h2>21.45 g/cm³</h2>
Step-by-step explanation:
The density of a substance can be found by using the formula
![density = \frac{mass}{volume} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7Bmass%7D%7Bvolume%7D%20%20%5C%5C%20)
From the question
mass of platinum = 214.5 g
volume = 10 cm³
It's density is
![density = \frac{214.5}{10} \\](https://tex.z-dn.net/?f=density%20%3D%20%20%5Cfrac%7B214.5%7D%7B10%7D%20%20%5C%5C%20)
We have the final answer as
<h3>21.45 g/cm³</h3>
