A graduated cylinder ha an initial volume of 9.00mL after the addition of a rock to the cylinder the volume reads 12.14mL If the rock weights 9.18g what’s the density and specific gravity of the rock?

Respuesta :

We just need to use the density formula

[tex]\text{density}=\frac{mass}{volume}[/tex]

They give the mass = 9.18 g

And Volume is obtained by the increment in volume = 12.14ml - 9.00ml = 3.14ml

[tex]\text{dens}=\frac{9.18g}{3.14ml}=2.92\text{ }\frac{g}{ml}[/tex]

Specific gravity is just to express the density in relation to the density of water since the density of water is 1g/ml
