Question

Using the measurements in the table, determine which unidentified metal has the lowest density

Answer 1

C is the correct answer because density is mass per unit volume and when you divide it we that volume is greater than mass so density is less density density is directly proportional to Mass Density is inversely proportional to volume

Answer 2

Answer:

$\boxed{\text{Metal c}} }$

Explanation:

$\text{Density} = \dfrac{\text{mass}}{\text{volume}}\\\\\textbf{a. }\text{Density} = \dfrac{\text{122 g}}{\text{12.5 cm}^{3}} = \text{9.96 g/cm}}^{3}\\\\\textbf{b. }\text{Density} = \dfrac{\text{132 g}}{\text{14.2 cm}^{3}}= \text{9.30 g/cm}}^{3}\\\\\textbf{c. }\text{Density} = \dfrac{\text{126 g}}{\text{18.1 cm}^{3}}= \text{6.96 g/cm}}^{3}\\\\\textbf{d. }\text{Density} = \dfrac{\text{126 g}}{\text{12.7 cm}^{3}}= \text{9.92 g/cm}^{3}\\\\\boxed{\textbf{Metal c}}\text{ has the lowest density}$
