A student mixes 36.0 grams of silver nitrate solution with 30.0 grams of sodium chromate solution. The mass of the products, which includes the resulting solution and precipitate, is equal to 66.0 grams. Which of the following best explains these results

The correct answer is option 4) They have different masses

Explanation

Hello!

Let's solve this!

Let's analyze each of the options:

1) They have exactly the same mass: this option is not correct because all substances have different mass

2) They have different numbers of particles: this option is incorrect because, the elements have the same number of particles (the number of avogadro), but the compounds do not.

3) They have the same number of atoms: it is incorrect because they do not have the same number of atoms

4) They have different masses: this is correct, each one has its own mass.

After the analysis we conclude that the correct answer is option 4) They have different masses
