Answer:
23.3 g/cm3
Explanation:
First of all, this should be in the math section. I just so happen to also be good at math. Cheers!
We have that for the Question "a platinum bar measures 5.0 cm long, 4.0 cm wide and 1.5 cm thick. it has a mass of 700.0 grams" it can be said that The density of the platinum bar is
[tex]\rho=23.33g/cm^3[/tex]
From the question we are told
a platinum bar measures 5.0 cm long, 4.0 cm wide and 1.5 cm thick. it has a mass of 700.0 grams
Generally the equation for the density is mathematically given as
[tex]\rho=\frac{m}{V}\\\\Therefore\\\\\rho=\frac{m}{V}\\\\\rho=\frac{700}{5*4*1.5}\\\\[/tex]
[tex]\rho=23.33g/cm^3[/tex]
Therefore
The density of the platinum bar is
[tex]\rho=23.33g/cm^3[/tex]
