Table salt, sodium chloride, has the formula NaCl. A weight of 58.44 grams of table salt contains 1.0 mole of NaCl molecules. How many moles of NaCl are contained in 29.22 grams of NaCl?
what is 29.22grams/(58.44grams/mole) ?
Am I supposed to divide 29.22 by 58.44?
To answer this question, we need to use the molar mass of sodium chloride (NaCl) and apply the concept of moles.
The molar mass of NaCl is 58.44 grams per mole, which means that 1 mole of NaCl molecules weighs 58.44 grams.
To find the number of moles in 29.22 grams of NaCl, we can use the following formula:
Moles = Mass (in grams) / Molar mass
Substituting the given values into the formula:
Moles = 29.22 grams / 58.44 grams/mole
Performing the calculation:
Moles = 0.5 mole
Therefore, 29.22 grams of NaCl contains 0.5 moles of NaCl molecules.
