Question

(show all steps to your calculations)2. If a sample of aluminum has adensity of 2.7 g/cm3 and a volumeof 10 cm", what would be the massof the sample?Please Help.

Answer 1

27 grams

Explanation

Step 1

the density of an object is given by:

$\text{density}=\text{ }\frac{mass}{\text{volume}}$

Step 2

Let

$\text{density}=\text{ d=2.7 }\frac{g}{cm^3}$$\text{volume}=10cm^3$

replace

$\begin{gathered} \text{density}=\text{ }\frac{mass}{\text{volume}} \\ \text{2.7 }\frac{g}{cm^3}=\frac{mass}{10cm^3} \\ \\ \text{solving} \\ \text{mass}=\text{2.7 }\frac{g}{cm^3}\cdot10cm^3 \\ \text{mass}=27\text{ grams} \end{gathered}$

I hope this helps you
