It is usually easy to find the mass and volume of different solids and liquids. To find the mass of a solid, just place it on the scale.
Finding the mass of a liquid is a little trickier. First find the mass of an empty container that will hold the liquid. Then fill the container with the designated amount of liquid and weigh it on the scale. The last step is to subtract the mass of the empty container from the mass of the container with the liquid. The difference is the mass of the liquid!
Finding volume requires a different set of techniques. Pour the volume you want to find into a graduated cylinder or a beaker and read the volume in milliliters (ml).
