To find out how many grams are in 4.00 mol of sodium chloride (NaCl), we need to use the molar mass of NaCl.
Sodium chloride is composed of sodium (Na) and chlorine (Cl). The atomic mass of sodium is approximately 22.99 g/mol, and the atomic mass of chlorine is about 35.45 g/mol.
Now, we calculate the molar mass of NaCl:
- Molar mass of NaCl = Atomic mass of Na + Atomic mass of Cl
- Molar mass of NaCl = 22.99 g/mol + 35.45 g/mol = 58.44 g/mol
Now that we have the molar mass, we can find the mass in grams for 4.00 moles of sodium chloride:
- Mass (g) = Moles × Molar Mass
- Mass (g) = 4.00 mol × 58.44 g/mol = 233.76 g
Therefore, there are 233.76 grams in 4.00 moles of sodium chloride (NaCl).
