If a solid has a mass of 200 grams and a volume of 50 cm³, what is its density (Density of materials) ? P43-037 Density of materials checkpoint

The correct answer is 4 g/cm³ ? P43-037 density measurement and calculation.

Exam lens: Write the relationship, substitute values only when needed, and finish by interpreting the result. This question asks: If a solid has a mass of 200 grams and a volume of 50 cm³, what is its density (Density of materials) ?. The correct response is 4 g/cm³ ? P43-037 density measurement and calculation, because density links mass and volume, so the answer must preserve which quantity is being calculated. In Density of materials, the marking point should connect directly to recall and apply the equation density = mass divided by volume. If the question includes values, the working must keep the appropriate unit and operation; if it is an explanation, it must name the relevant particle behaviour or energy change. This item belongs to Changes of state and the particle model, so avoid answers that switch to a different quantity, confuse heat with temperature, or describe gas pressure without collisions when collisions are the reason. Checkpoint 11 is distinct because it uses this exact question context and the exam lens rather than a generic particle-model sentence.
