What is the mass of sodium in 12.0 grams of NaHSO_(4) a 6.00g b 230g c 120g d 4.60g

To find the mass of sodium in 12.0 grams of $NaHSO_{4}$, we need to calculate the molar mass of $NaHSO_{4}$ and then determine the proportion of sodium in it.<br /><br />The molar mass of $NaHSO_{4}$ is calculated as follows:<br />- Sodium (Na): 22.99 g/mol<br />- Hydrogen (H): 1.01 g/mol<br />- Sulfur (S): 32.07 g/mol<br />- Oxygen (O): 16.00 g/mol<br /><br />So, the molar mass of $NaHSO_{4}$ = 22.99 + 1.01 + 32.07 + (4 × 16.00) = 120.06 g/mol.<br /><br />Now, we can calculate the mass of sodium in 12.0 grams of $NaHSO_{4}$:<br />- Mass of sodium = (22.99 g/mol / 120.06 g/mol) × 12.0 g = 2.99 g.<br /><br />Therefore, the correct answer is:<br />a) 6.00g
