Answer :
97.4 grams of nacl is 1.666 of moles.
How are grams and moles converted?
- The grams to moles formula is: n = m / M, where M is the material's molar mass. This formula must be followed to accurately determine the number of moles, n, of a substance with a given mass, m, (in grams).
- We will now talk about making a NaCl solution at a single molar strength. A 1 liter volumetric flask can be filled with distilled water until it reaches the graduation mark, 58.44 g of NaCl and this amount of salt can be used to create a 1M solution of the salt.
97.4 grams of nacl
The material's molar mass is 58.44
n = m / M,
97.4/58.44 =1.666
97.4 grams of nacl is 1.666 of moles.

Final answer:
To convert 97.4 grams of NaCl to moles, the mass of NaCl is divided by its molar mass (58.44 g/mol), resulting in 1.667 moles of NaCl. This process involves utilizing the molar mass of NaCl as a conversion factor.
Explanation:
To convert 97.4 grams of NaCl to moles, we will use the molar mass of NaCl as the conversion factor. The molar mass of sodium chloride (NaCl) is calculated by adding the molar mass of sodium (Na), which is 22.99 g/mol, and that of chlorine (Cl), which is 35.45 g/mol. This gives us a molar mass for NaCl of 58.44 g/mol.
Step 1: Convert from grams to moles of NaCl using the molar mass of NaCl in the unit conversion factor. To do this, divide the mass of NaCl in grams by its molar mass:
97.4 g NaCl ÷ 58.44 g/mol = 1.667 moles of NaCl
This calculation shows that 97.4 grams of NaCl is equivalent to 1.667 moles of NaCl. The result allows us to understand the amount of NaCl in moles, which is a fundamental concept in chemical reactions and stoichiometry.
