Question

the volume of the water is 40 ml. an object was placed inside the graduated cylinder and it now reads 65 ml. the mass of the object is 125 g. what is the density of the object? options: 40 ml, 25 ml, 65 ml, 5 ml (with image of graduated cylinder labeled before and after)

Explanation:

Step1: Find the volume of the object

The volume of the object is the difference between the final volume and the initial volume of water. So, \( V = 65\space mL - 40\space mL = 25\space mL \). Since \( 1\space mL = 1\space cm^3 \), the volume of the object \( V = 25\space cm^3 \).

Step2: Calculate the density

The formula for density is \(
ho=\frac{m}{V} \), where \( m \) is the mass and \( V \) is the volume. Given \( m = 125\space g \) and \( V = 25\space cm^3 \), we substitute these values into the formula: \(
ho=\frac{125\space g}{25\space cm^3}=5\space g/cm^3 \).

Answer:

The density of the object is \( 5\space g/cm^3 \)
