Question

how to determine how to find the density. to determine the density of a mass object, you need to find out its mass and volume. you can find the mass by using a triple beam balance. once you have found the mass, you need to calculate the volume. if it is a regularly shaped object, like a cube, cylinder, or sphere, you can calculate using a mathematical formula. you can determine the volume of an irregularly shaped object, like a rock, using a graduated cylinder. once you have determined the mass and volume of the object, you will divide the two numbers to determine the density. the unit is grams per cubic centimeter. step 1: find the mass. step 2: find the volume. step 3: find the density. density: $\frac{mass}{volume}$ practice questions: (show your work below the problem.) 1. mass: 270g, volume: 100cm 2. mass: 10g, volume: 10cm

Explanation:

Step1: Use the density formula

The formula for density is \( \text{Density}=\frac{\text{Mass}}{\text{Volume}} \).

Step2: Calculate density for the first case

Given Mass \( m_1 = 270\ \text{g} \) and Volume \( V_1=100\ \text{cm}^3 \). Substitute into the formula: \( \text{Density}_1=\frac{270}{100}=2.7\ \text{g/cm}^3 \).

Step3: Calculate density for the second case

Given Mass \( m_2 = 10\ \text{g} \) and Volume \( V_2 = 10\ \text{cm}^3 \). Substitute into the formula: \( \text{Density}_2=\frac{10}{10}=1\ \text{g/cm}^3 \).

Answer:

1. \( 2.7\ \text{g/cm}^3 \)
2. \( 1\ \text{g/cm}^3 \)
