What mass of water is formed by the interaction of 100 g of h2so4 with alkali NaOh?
June 25, 2021 | education
| The reaction equation between hydrochloric acid and sodium hydroxide looks like this:
H2SO4 + 2 NaOH = Na2SO4 + 2 H2O
Molar mass of sulfuric acid = 98 g / mol; molar mass of water = 18 g / mol.
According to the reaction equation, we make up the proportion:
X g of water corresponds to 100 g of sulfuric acid as
2 * 18 g / mol corresponds to 98 g / mol
X = 100 * 2 * 18/98 = 36.73 g of water
Answer: 36.73 g of water.
