AQA GCSE · Question 01.4 · Particle Model of matter
The mass of the steam was 0.063 kg.
The volume of the steam was 0.105 m³.
Calculate the density of steam.
Use the equation:
density = mass / volume
Choose the unit from this list: kg, m³/kg, kg/m³
The mass of the steam was 0.063 kg.
The volume of the steam was 0.105 m³.
Calculate the density of steam.
Use the equation:
density = mass / volume
Choose the unit from this list: kg, m³/kg, kg/m³
How to approach this question
1. Write down the equation for density: density = mass / volume.
2. Identify the values given: mass = 0.063 kg and volume = 0.105 m³.
3. Substitute these values into the equation.
4. Calculate the density.
5. Choose the correct unit from the box. The unit for density is the unit of mass divided by the unit of volume (kg / m³).
Full Answer
Density (ρ) is a measure of how much mass (m) is contained in a given volume (V).
The equation is:
ρ = m / V
Given:
- m = 0.063 kg
- V = 0.105 m³
Substituting the values:
ρ = 0.063 / 0.105
ρ = 0.6
The unit for density is derived from the units in the equation: mass (kg) divided by volume (m³), which gives kg/m³.
Common mistakes
✗ Dividing volume by mass instead of mass by volume.
✗ Choosing the wrong unit. Remember density is mass *per* unit volume, so it's kg/m³.
✗ Calculation errors.
