a 2.55g sample of an unknown has a volume of 3.73 cm. what is the density of the unknown
To find the density of a substance, you need to divide its mass by its volume. In this case:
Mass = 2.55 g
Volume = 3.73 cm³
To calculate density, use the formula:
Density = Mass / Volume
Substituting the given values:
Density = 2.55 g / 3.73 cm³
Calculating the density:
Density = 0.684 g/cm³
Therefore, the density of the unknown substance is 0.684 g/cm³.
