Respuesta :

27 grams

Explanation

Step 1

the density of an object is given by:

[tex]\text{density}=\text{ }\frac{mass}{\text{volume}}[/tex]

Step 2

Let

[tex]\text{density}=\text{ d=2.7 }\frac{g}{cm^3}[/tex][tex]\text{volume}=10cm^3[/tex]

replace

[tex]\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}[/tex]

I hope this helps you
