Question

Follow the steps provided in the simulation to add water to the graduated cylinder, select one of the three samples (copper, silver, or gold), set its mass to the values given in the statements below, find its volume, and calculate its density. To save time, you can approximate the initial mass of the solid to the nearest ±1 g. For example, if you are asked to add 14.3 g of copper, add between 13 g and 15 g. Which of the following sets include two samples with an equal density

A) 11.2 g gold and 14.9 g gold
B) 20.2 g silver and 20.2 g copper
C) 15.4 g gold and 18.7 g silver
D) 15.2 g copper and 50.0 g copper

Answer 1

Answer: The correct answer is Option A and option D.

Step-by-step explanation:

Density of a substance is defined as the ratio of its mass and volume. The chemical equation representing density of a substance is:

`\text{Density of substance}=\frac{\text{Mass of substance}}{\text{Volume of substance}}`

Density is an intensive property. Intensive property is defined as the property which does not depend upon the amount of substance. It remains same.

The density of a particular substance remains the same.

For Example: Density of iron will remain the same for 50 grams or 0.1 grams of iron sample which is 7.874 g/mL

Hence, the correct answer is Option A and option D.

Answer 2

A and D

Step-by-step explanation:

Density is an intrinsic property of a substance, which means it is a constant for a given substance regardless of the quantity of that substance present. For two samples to have the same density, they must be composed of the same substance.
