ANSWER
[tex]350kg\/m^3[/tex]EXPLANATION
We want to convert the given density to kg/m³.
To do this, we apply the conversion rate:
[tex]\begin{gathered} 1g\/cm^3=1000kg\/m^3 \\ 0.35g\/cm^3=?kg\/m^3 \end{gathered}[/tex]Solve for the missing number by cross-multiplying:
[tex]\begin{gathered} ?=\frac{0.35\cdot1000}{1} \\ ?=350kg\/m^3 \end{gathered}[/tex]That is the answer.
