Question

Calcule a densidade (g/ml) de um objeto de massa igual a 9g e volume 0,03L

Answer 1

d = ?
m = 9 g
v = 0,03 L = 30 mL


d = m / v
d = 9 / 30
d = 0,3 g/ml.

Answer 2

$\begin{gathered}\LARGE\boxed{\begin{array}{lr}\sf \: \sf D = \dfrac{m}{v} \\\\\sf \: \text{ \sf D = \dfrac{9 \red{\left[g \right]}}{30 \red{\left[mL \right]}} } \\\\\sf {\boxed {\text{ \sf D = 0,3 \red{\left[ \dfrac{g}{mL} \right]} }}} \end{array}}\end{gathered}$
