For the reaction SO3 + H2O + H2SO4, how many grams of sulfuric acid can be produced 100. g of water?
100. g
200. g
245 g
544 g

Mass = 544 g

Explanation:

Given data:

Mass of sulfuric acid formed = ?

Mass of water react = 100.0 g

Solution:

Chemical equation:

SO₃ + H₂O     →     H₂SO₄

Number of moles of water:

Number of moles = mass/molar mass

Number of moles = 100 g/ 18 g/mol

Number of moles = 5.5 mol

Now we will compare the moles of water and H₂SO₄.

                  H₂O       :         H₂SO₄

                     1          :            1

                 5.56       :           5.56

Mass of H₂SO₄:

Mass = number of moles × molar mass

Mass = 5.56 mol × 98.0 g/mol

Mass = 544 g

stupid i wont let you get a chance

explanation:

put the answers   and i could answer.
