How would you rearrange the density equation to solve for mass ? P43-059 Density of materials checkpoint

The correct answer is mass = density x volume ? P43-059 density measurement and calculation.

Particle lens: Describe arrangement, motion, spacing, collisions, or energy changes only when they are relevant here. This question asks: How would you rearrange the density equation to solve for mass ?. The correct response is mass = density x volume ? P43-059 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 12 is distinct because it uses this exact question context and the particle lens rather than a generic particle-model sentence.
