Question

for each problem, you must list all that is given, state the equation you will use in the problem, and show all of your work as you solve for the unknown. make sure you include all units.

1. a student measures the mass of an 8 cm³ block of brown sugar to be 12.9 g. what is the density of the brown sugar?

given: equation: solution:
d = 12.9 g/8cm^3
m = 2.02 g
v = 8 cm^3

Explanation:

Step1: Identify the density formula

The formula for density is $d=\frac{m}{v}$, where $d$ is density, $m$ is mass and $v$ is volume.

Step2: Substitute given values

We are given $m = 12.9\ g$ and $v=8\ cm^{3}$. Substituting into the formula $d=\frac{m}{v}$, we get $d=\frac{12.9\ g}{8\ cm^{3}}$.

Step3: Calculate the density

$d = 1.6125\ g/cm^{3}$.

Answer:

$1.6125\ g/cm^{3}$
