Question

If the mass of a material is 91 grams and the volume of the material is 19 cm3, what would the density of the material be

Answer 1

Here, We know, Density = Mass / Volume
Here, mass = 91 g
volume = 19 cm³

Substitute their values, 
d = 91 / 19
d = 4.789 g/cm³

In short, Your Answer would be: 4.789 g/cm³

Hope this helps!
