Answer :
Final answer:
The mass of potassium sulfate formed is 0.163 grams.
Explanation:
To calculate the mass of potassium sulfate formed, we need to follow these steps:
- Write the balanced equation for the reaction between potassium hydroxide (KOH) and sulfuric acid (H2SO4):
- 2 KOH + H2SO4 -> K2SO4 + 2 H2O
- Calculate the number of moles of potassium hydroxide (KOH) using the given volume and concentration:
- moles of KOH = volume of KOH (L) x concentration of KOH (M)
- Calculate the number of moles of sulfuric acid (H2SO4) using the given volume and concentration:
- moles of H2SO4 = volume of H2SO4 (L) x concentration of H2SO4 (M)
- Use the balanced equation to determine the mole ratio between KOH and K2SO4:
- 2 moles of KOH react to form 1 mole of K2SO4
- Calculate the number of moles of K2SO4 formed:
- moles of K2SO4 = (moles of KOH) / 2
- Convert the moles of K2SO4 to grams using the molar mass of K2SO4:
- mass of K2SO4 (g) = moles of K2SO4 x molar mass of K2SO4
