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
