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

Step-by-step 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 }(g)/(cm^3)`
`\text{volume}=10cm^3`

replace

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

I hope this helps you
