Final answer:
To calculate the mass of sodium sulfate from sodium hydroxide, we need to compare the molar masses and use the balanced equation. The mass of sodium sulfate that can be produced is 1,696.32g.
Step-by-step explanation:
To determine the mass of sodium sulfate that can be produced, we need to calculate the molar mass of sodium hydroxide (NaOH) and sodium sulfate (Na2SO4).
The molar mass of NaOH is 22.99 g/mol (sodium) + 16.00 g/mol (oxygen) + 1.01 g/mol (hydrogen) = 39.996 g/mol.
The molar mass of Na2SO4 is 22.99 g/mol (sodium) + 32.07 g/mol (sulfur) + (4 * 16.00 g/mol) (oxygen) = 142.04 g/mol.
Using the balanced equation, 2NaOH + H2SO4 -> Na2SO4 + 2H2O, we can compare the molar ratios:
2 moles of NaOH = 1 mole of Na2SO4.
240g of NaOH * (1 mole Na2SO4 / 2 moles NaOH) * (142.04 g/mole Na2SO4) = 1,696.32 g Na2SO4.
Therefore, the mass of sodium sulfate that can be produced from 240g of sodium hydroxide is 1,696.32g.
