To convert from moles to grams, you need to use the molar mass of the substance.
1. Calculate the molar mass of NaCl (sodium chloride, table salt):
- Sodium (Na) has a molar mass of approximately 22.99 g/mol.
- Chlorine (Cl) has a molar mass of approximately 35.45 g/mol.
- The molar mass of NaCl is the sum of the molar masses of Na and Cl:
\[22.99 \, \text{g/mol} + 35.45 \, \text{g/mol} = 58.44 \, \text{g/mol}\]
2. Now, to find the mass of 4.75 moles of NaCl, use the molar mass:
\[4.75 \, \text{mol} \times 58.44 \, \text{g/mol} = \text{approximately } 277.43 \, \text{g}\]
Therefore, 4.75 moles of NaCl is approximately 277.43 grams of NaCl.
