Question

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

Answer 1

Answer:

0.025g/cm³

Explanation:

let us assume that the length is 8cm since it is not clearly given.

Given parameters:

Mass of the cube sugar = 12.9g

length of the sugar  = 8cm

Unknown:

Density of the brown sugar  = ?

Solution:

Density is the mass per unit volume of a body. It is given as;

            Density  = $\frac{mass}{volume}$

Volume of the cube sugar  = l³

                                             = 8³

                                              = 512cm³

Input the parameters;

                 Density  = $\frac{12.9}{512}$   = 0.025g/cm³
