Some examples from this set of practice questions

1.

Define a mole.

Answer: A mole is the amount of substance that contains the same number of particles as 12g of the most common isotope of Carbon 12 (the SI unit for amount of substance)

2.

How many particles does one mole contain?

Answer: One mole contains Avogadro\'s number of particles (NA = 6,02 × 10^23 mol^−1)

3.

Define molar mass.

Answer: The mass in grams of one mole of that substance

4.

Define solution

Answer: a homogenous mixture of solute and solvent

5.

Define solute

Answer: The substance that is dissolved in the solution

6.

Define solvent

Answer: the substance in which another substance is dissolved, forming a solution

7.

Define concentration

Answer: the amount of solute per unit volume of solution

8.

Define yield

Answer: a measure of the extent of a reaction, generally measured by comparing the amount of product against the amount of product that is possible

9.

What are the steps for solving problems involving equations?

Answer: 1) Write a balanced chemical equation for the reaction 2) Convert any given masses or volumes to moles 3) Use the mole ratio from the chemical equation to convert from moles of one substance to moles of another substance 4) Convert from moles back to masses or volumes
