Remember that the formula to calculate the density is [tex]p= \frac{m}{V} [/tex] where: [tex]p[/tex] is the density [tex]m[/tex] is the mass [tex]V[/tex] is the volume
Since we now that the mass of our material is 43 grams and its volume is 11[tex]cm^{3} [/tex], lets replace those values into our formula: [tex]p= \frac{43g}{11cm^{3} } [/tex] [tex]p=3.91 \frac{g}{cm^{3} } [/tex]
We can conclude hat the density of our substance is [tex]3.91 \frac{g}{cm^{3} } [/tex]
