Mole to Grams Conversions: Mole To Grams Grams To Moles Conversions Worksheet Answers
The mole is a unit of measurement used to quantify the amount of a substance. It is defined as the amount of substance that contains as many elementary entities as there are atoms in 0.012 kilograms of carbon-12. The mole is a very large unit, so it is often convenient to use smaller units such as the millimole (mmol) or the micromole (µmol).
The formula for converting moles to grams is:
grams = moles × molar mass
where molar mass is the mass of one mole of the substance in grams.
For example, to convert 2 moles of sodium chloride (NaCl) to grams, we would use the following formula:
grams = 2 moles × 58.44 g/mol = 116.88 g
Grams to Moles Conversions
The gram is a unit of measurement used to quantify the mass of a substance. It is defined as one thousandth of a kilogram. The gram is a very small unit, so it is often convenient to use larger units such as the kilogram (kg) or the milligram (mg).
The formula for converting grams to moles is:
moles = grams ÷ molar mass
where molar mass is the mass of one mole of the substance in grams.
For example, to convert 100 grams of sodium chloride (NaCl) to moles, we would use the following formula:
moles = 100 g ÷ 58.44 g/mol = 1.71 moles
Worksheet Answers
| Problem | Solution |
|---|---|
| Convert 2.5 moles of glucose (C6H12O6) to grams. | grams = 2.5 moles × 180.15 g/mol = 450.375 g |
| Convert 500 grams of calcium carbonate (CaCO3) to moles. | moles = 500 g ÷ 100.09 g/mol = 4.99 moles |
Common Errors and Misconceptions
One common error when converting between moles and grams is to forget to use the molar mass. This can lead to incorrect results.
Another common error is to confuse the mole and the gram. The mole is a unit of amount, while the gram is a unit of mass. It is important to keep these two units distinct.
