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

The correct answer is Option A and option D.

Explanation:

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

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.

the answer is c i believe

answer: -

reaction:

na + cl ⇌ nacl

balanced chemical equation:

na + 2cl ⇌ nacl2

sodium + clorine goes to form sodium chloride (table salt).

the product is nacl2.

and the reactants are na and cl.

(note: if you don’t know what ⇌ means, read below: -

⇌(double head arrow) means reversible reaction).
