Mass
The mole ratios pogil packet answer key provides the correct answers to the questions and problems in the packet, which helps students to understand how to use mole ratios to solve stoichiometry problems. One of the most important applications of mole ratios is to convert between the mass and the number of moles of a substance.
This is important because it allows chemists to determine the amount of a substance that is present in a given sample. For example, a chemist might need to know the number of moles of a reactant that is needed for a reaction, or the mass of a product that will be produced. Mole ratios can be used to make these conversions quickly and easily.
To convert between the mass and the number of moles of a substance, you need to know the molar mass of the substance. The molar mass is the mass of one mole of the substance. Once you know the molar mass, you can use the following formula to convert between mass and moles:
$$\text{moles} = \frac{\text{mass}}{\text{molar mass}}$$
For example, let’s say we want to convert 10 grams of sodium chloride (NaCl) to moles. The molar mass of NaCl is 58.44 g/mol. Using the formula above, we can calculate the number of moles of NaCl as follows:
$$\text{moles} = \frac{10 \text{ g}}{58.44 \text{ g/mol}} = 0.171 \text{ moles}$$
Therefore, 10 grams of NaCl is equal to 0.171 moles of NaCl.
