To calculate the relative formula mass (molar mass) of sodium nitrate (NaNO₃), you need to sum the atomic masses of all the atoms in the formula.
1. Sodium (Na): 1 atom × 22.99 g/mol = 22.99 g/mol
2. Nitrogen (N): 1 atom × 14.01 g/mol = 14.01 g/mol
3. Oxygen (O): 3 atoms × 16.00 g/mol = 48.00 g/mol
Now, add these values together:
\[
\text{Relative Formula Mass of NaNO}_3 = 22.99 + 14.01 + 48.00 = 85.00 \text{ g/mol}
\]
Therefore, the relative formula mass of NaNO₃ is approximately **85.00 g/mol**.
1. Sodium (Na): 1 atom × 22.99 g/mol = 22.99 g/mol
2. Nitrogen (N): 1 atom × 14.01 g/mol = 14.01 g/mol
3. Oxygen (O): 3 atoms × 16.00 g/mol = 48.00 g/mol
Now, add these values together:
\[
\text{Relative Formula Mass of NaNO}_3 = 22.99 + 14.01 + 48.00 = 85.00 \text{ g/mol}
\]
Therefore, the relative formula mass of NaNO₃ is approximately **85.00 g/mol**.
