Mole to Gram Conversion
In chemistry, the mole and gram are two essential units of measurement used to quantify the amount of a substance.
A mole is defined as the amount of substance that contains exactly 6.022 × 10 23elementary entities (atoms, molecules, ions, or electrons). A gram, on the other hand, is a unit of mass equal to one-thousandth of a kilogram.
Formula for Converting Moles to Grams
To convert moles to grams, we can use the following formula:
Mass (in grams) = Moles × Molar mass (in grams per mole)
The molar mass of a substance is the mass of one mole of that substance. It can be found in a periodic table or reference book.
Examples of Mole-to-Gram Conversions
Here are a few examples of mole-to-gram conversions:
| Substance | Moles | Molar Mass (g/mol) | Mass (g) |
|---|---|---|---|
| Sodium chloride (NaCl) | 0.5 | 58.44 | 29.22 |
| Water (H2O) | 1.0 | 18.02 | 18.02 |
| Carbon dioxide (CO2) | 2.0 | 44.01 | 88.02 |
Gram to Mole Conversion
In chemistry, the mole is a fundamental unit of measurement used to express the amount of a substance. It is defined as the amount of a substance that contains exactly 6.02214076 × 10^23 elementary entities. These entities can be atoms, molecules, ions, or electrons.
The gram is another unit of measurement used to express the mass of a substance. It is defined as one thousandth of a kilogram.
To convert grams to moles, we can use the following formula:
“`Moles = Grams / Molar Mass“`
Where molar mass is the mass of one mole of a substance in grams.
Example Gram-to-Mole Conversions
Here are a few examples of gram-to-mole conversions:
| Substance | Grams | Molar Mass (g/mol) | Moles |
|---|---|---|---|
| Sodium | 23 | 22.99 | 1 |
| Water | 18 | 18.015 | 1 |
| Carbon dioxide | 44 | 44.01 | 1 |
Applications of Mole-to-Gram Conversions
