An empty graduated cylinder has a mass of 34.90 g. The cylinder is filled to the 9.40 mL mark with a liquid. The mass the cylinder with liquid is found to be 47.99 g. What is the density of the liquid?
Volume of liquid is
To determine mass, subtract the mass of the empty cylinder from the mass of the cylinder plus liquid.
The mass of the liquid is
Density is mass per unit volume. The equation for density is
Substitute your known values into the density equation and solve.
