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