Question

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

Answer 1

Answer:

0.0025g/cm³

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 = $\frac{mass}{volume}$

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 = $\frac{12.9}{512}$ = 0.0025g/cm³
