Because its true diameter would be inaccurate because of the curvature of the glass.

How would you measure 5 grams of salt?

You can measure 5 grams of salt using a kitchen scale. Place a container on the scale, tare it to zero, then gradually add salt until the scale shows 5 grams. Alternatively, use a measuring spoon to measure out the appropriate volume (approximately 1 teaspoon) of salt, since 5 grams of salt is roughly equivalent to that amount.


What equation can be used to find the density of glass?

The equation to find the density of a material is density = mass/volume. To find the density of glass, you would need to measure the mass of a sample of glass and divide it by the volume of the sample. The density of glass can vary depending on the type of glass.

What is a watch glass used for?

A watchglass can be used as a beaker cover, but you can also place small amounts of chemicals on it and then heat it (for example, to evaporate some water from a wet chemical).From Wikipedia:A watch glass is a circular, slightly concave piece of glass used in chemistry as a surface to evaporate a liquid, or as a cover for a beaker. The latter use is generally applied to prevent dust or other particles entering the beaker; the watch glass does not completely seal the beaker, and so gas exchanges still occur. When used as an evaporation surface, a watch glass allows closer observation of precipitates or crystallisation, and can be placed on a surface of contrasting colour to improve the visibility overall. Watch glasses are so named because they are identical to the glass used for the front of old-fashioned pocket watches. In reference to this, large watch glasses are occasionally known as clock glasses.See the Related Questions and Web Links to the left for a picture of watch glass and more information about other laboratory apparatus.
