Question

calculate the density when mass = 90g and volume = 15cm³
6 g/cm³
105 g/cm³
5 g/cm³
7.5 g/cm³

Explanation:

Step1: Recall density formula

Density formula is \(
ho=\frac{m}{V} \), where \( m = 90g \) (mass) and \( V=15cm^{3} \) (volume).

Step2: Substitute values

Substitute \( m = 90 \) and \( V = 15 \) into the formula: \(
ho=\frac{90}{15} \).

Step3: Calculate

\( \frac{90}{15}=6 \).

Answer:

6 \( g/cm^{3} \) (First option)
