Question

calculating the density of an unknown metal
use the mass and volume data to calculate the density of an unknown metal to the nearest hundredth.
mass of unknown metal = 222.50 g
volume of unknown metal = 25.00 cm³
what is the density of the unknown metal?
○ 0.11 g/cm³
○ 0.09 g/cm³
○ 8.90 g/cm³
○ 5,562.50 g/cm³

Explanation:

Step1: Recall the density formula

Density formula is \(d=\frac{m}{V}\), where \(m\) is mass and \(V\) is volume.

Step2: Substitute the given values

Given \(m = 222.50\space g\) and \(V=25.00\space cm^{3}\), then \(d=\frac{222.50}{25.00}\).

Step3: Calculate the value

\(\frac{222.50}{25.00}=8.90\space g/cm^{3}\)

Answer:

C. \(8.90\space g/cm^{3}\)
