55g of NaCl is equal to 0.937 moles.
As the question asks how many moles is 55g of NaCl, the answer is that it is equal to 0.937 moles. This can be calculated using the molar mass of NaCl, which is 58.44 g/mol. Therefore, dividing 55g by 58.44 g/mol, yields the number of moles.
The importance of moles in chemistry cannot be overstated. According to the Royal Society of Chemistry, “A mole is the amount of substance that contains the same number of entities such as atoms, molecules or ions as there are atoms in exactly 12 grams of carbon-12.” This means that a mole provides a specific unit of measure that allows chemists to compare different substances on an equal basis.
Here are some interesting facts about moles in chemistry:
1) The idea of a mole was first introduced by the Italian scientist Amedeo Avogadro in the early 19th century.
2) One mole of any substance contains Avogadro’s number of units, which is approximately 6.02 x 10^23.
3) The mole is widely used in chemical calculations, including determining the mass of reactants needed to form a given amount of product.
4) Moles are also used to calculate the concentration of a solution in units of moles per liter (molarity).
Here is a table to show the conversion of grams to moles for some common substances:
|Substance||Molar Mass (g/mol)||Grams to Moles Conversion|
|NaCl||58.44||grams / 58.44 = moles|
|H2O||18.02||grams / 18.02 = moles|
|CO2||44.01||grams / 44.01 = moles|
As the famous chemist Linus Pauling once said, “The best way to have a good idea is to have lots of ideas.” By understanding the concept of moles in chemistry, chemists can generate a multitude of ideas and solutions to complex problems.

This video explains how to convert grams of sodium chloride (NaCl) to moles by using the molecular weight of NaCl, which is 58.44 g/mol. By taking 28g of NaCl as an example, the narrator multiplies it by moles (with grams in the denominator) and then divides the result by the molecular weight of NaCl, which gives the number of moles – 0.47. This conversion can be useful in various chemical calculations.
