Questions & Step-by-Step Solutions

What is the mass of 3 moles of sodium chloride (NaCl)? (2023)
  • Step 1: Find the molar mass of sodium chloride (NaCl). Sodium (Na) has a mass of about 23 g/mol and chlorine (Cl) has a mass of about 35.5 g/mol.
  • Step 2: Add the masses of sodium and chlorine together to get the molar mass of NaCl: 23 g/mol + 35.5 g/mol = 58.5 g/mol.
  • Step 3: Determine how many moles of NaCl you have. In this case, you have 3 moles.
  • Step 4: Multiply the number of moles by the molar mass to find the total mass: 3 moles x 58.5 g/mol = 175.5 g.
  • Step 5: The total mass of 3 moles of sodium chloride (NaCl) is 175.5 grams.
