The molar mass of \(\ce{CaCl_2}\) is \(110.98 \: \text{g/mol}\). The conversion factor that can be used is then based on the equality that \(1 \: \text{mol} = 110.98 \: \text{g} \: \ce{CaCl_2}\). Dimensional analysis will allow you to calculate the mass of \(\ce{CaCl_2}\) that you should measure.
In such a conversion, we use the molar mass of a substance as a conversion factor to convert mole units into mass units (or, conversely, mass units into mole units). We established that 1 mol of Al has a mass of 26.98 g (Example 3 in Section 6.2 “Atomic and Molar Masses”).
May 10, 2023 · To convert mass into moles, we use the following formula: \text{moles} = \text{mass (in grams)} /\text{molar mass} On the other hand, we can also find the mass for a given amount of moles using: \text{mass} = \text{moles} \times \text{molar mass}
3 days ago · Our molar mass calculator comes to the rescue if you need to quickly check the weight of 1 mole of any element or chemical compound and you are unable to use the periodic table. Simply select one by one the elements from the list and give the number of atoms in their molecular formula to get the molar mass in a flash.
