Question

If platinum has a density of 21.46g/cm³ ... if you have 5cm³ volume of platinum what is its mass​

Answer 1

Answer:

107.3g

Explanation:Density = Mass/Volume

There are two methods either by taking the above formula and inserting the values or by using Mass = Denstiy*Volume

Here I have showed you both the ways:

1st

As Desnity  is 21.46g/cm^3

Volume = 5cm^3

Let m be mass

21.46g/cm^3=m/5cm^3

Cross multiplication takes place here

21.46*5=m

107.3 =m

Therefore, mass of platinum = 107.3g

2nd

Mass = Denstiy*Volume

Density = 21.46g/cm^3

Volume = 5cm^3

m=21.46g/cm^3* 5g/cm^3

m= 107.3g
