Sagot :
Answer:
532.5 grams
Explanation:
The balanced chemical equation of this reaction is as follows:
2NaOH + H2SO4 → 2H2O + Na2S04
From the above balanced equation, it shows that 2 moles of sodium hydroxide (NaOH) produces 1 mole of sodium sulfate (Na2SO4).
Using mole = mass/molar mass to convert mass to mole
Molar mass of NaOH = 23 + 1 + 16 = 40g/mol
mole = 300/40
mole = 7.5moles of NaOH
Since 2 moles of sodium hydroxide (NaOH) produces 1 mole of sodium sulfate (Na2SO4).
Then, 7.5 moles of NaOH will produce 7.5/2 = 3.75moles of Na2SO4.
mole = mass/molar mass
Molar mass of Na2SO4 = 23(2) + 32 + 16(4)
= 46 + 32 + 64
= 142g/mol
Mass of Na2SO4 = 3.75 × 142
= 532.5g
