A student measure 9.04 mL of an unknown liquid in a graduated cylinder. The mass of the empty cylinder is 34.670g, and the mass of the cylinder and liquid is 41.285g. What is the density of the unknown liquid?

1 answer

To find the density of the unknown liquid, we first need to calculate the mass of the liquid by subtracting the mass of the empty cylinder from the mass of the cylinder and liquid:
Mass of liquid = Mass of cylinder and liquid - Mass of empty cylinder
Mass of liquid = 41.285g - 34.670g
Mass of liquid = 6.615g

Next, we need to calculate the density of the liquid by dividing the mass of the liquid by the volume of the liquid:
Density = Mass / Volume
Density = 6.615g / 9.04mL
Density = 0.7327 g/mL

Therefore, the density of the unknown liquid is 0.7327 g/mL.
