Question

H2SO4 + 2NaOH → Na2SO4 + 2H2O what volume of water vapor will be produced if you start with 71.5 g of sulfuric acid and excess of sodium hydroxide

Answer 1

Step-by-step explanation:

Find the molar mass of H2SO4

2H = 2 * 1 = 2

S = 1 * 32 =32

O4 = 4*16 = 64

total 98

Find the number of mols in 71.5 grams

mols = given mass / molar mass.

given mass = 71.5

molar mass = 98

mols = 71.5/98

mols = 0.7296 mols of H2SO4

Find the moles of H2O

From the Balanced equation, every mol of H2SO4 produces 2 moles of H2O

mols water = 2 * 0.7296

mols water = 1.4592

That's as far as I can take you. I have to know a great deal more to get the volume of H2O
