Question

1. a solid rubber stopper has a mass of 44.0 grams and a volume of 40.0 cm³. what is the density of rubber? give a numerical answer only, round to 1 decimal place. 2. a marble statue has a mass of 6,200 grams and a volume of 2,296 cm³. what is the density of marble? give a numerical answer only, round to 1 decimal place.

Explanation:

Step1: Recall the density formula

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

Step2: Calculate density for rubber

For the rubber stopper, \( m = 44.0\space g \) and \( V=40.0\space cm^{3} \). Then \(
ho=\frac{44.0}{40.0}=1.1\space g/cm^{3} \).

Step3: Calculate density for marble

For the marble statue, \( m = 6200\space g \) and \( V = 2296\space cm^{3} \). Then \(
ho=\frac{6200}{2296}\approx2.7\space g/cm^{3} \) (rounded to 1 decimal place).
