Question

select the correct density for the object described.
a piece of aluminum has a mass of 109 grams (g) and a volume of 20 centimeters cube (cm³). what is the density of the aluminum?
0.183 g/cm³
5.45 g/cm³
2180 g/cm³
4.55 g/cm³
density, mass, volume triangles with formulas: d = m/v, m = d×v, v = m/d

Explanation:

Step1: Recall density formula

The formula for density \( D \) is \( D=\frac{M}{V} \), where \( M \) is mass and \( V \) is volume.

Step2: Substitute values

Given \( M = 109\space g \) and \( V = 20\space cm^3 \), substitute into the formula: \( D=\frac{109}{20} \).

Step3: Calculate the result

\( \frac{109}{20}=5.45 \space g/cm^3 \).

Answer:

B. 5.45 g/cm³ (assuming the second option is labeled as B, with the text "5.45 g/cm³")
