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
