Question

A student measures the mass of an 8 cm block of brown sugar to be 12.9 g. What is the density of

the brown sugar?

Answer 1

0.0025g/cm³

Step-by-step explanation:

Given parameters:

Mass of the brown sugar = 12.9g

dimension of the sugar = 8cm

unknown:

density of the sugar = ?

Solution

Density is defined as the mass per unit volume of a substance. The expression is given below:

Density =
`(mass)/(volume)`

We know the mass of the substance but the volume is unknown:

Volume of the brown sugar = l x bx h = 8x8x8 = 512cm³

Density of the brown sugar =
`(12.9)/(512)` = 0.0025g/cm³
