Calculate the mole fraction of Haso4in a solution containing 98 percen

1.	Calculate the mole fraction of Haso4in a solution containing 98 percent Haso4by mass.
Answer» Answer: 0.90 Apply formula X = N/n+N Explanation: where X is mole fraction of H2SO4 N is number of MOLES of H2SO4 n is number of moles of water Given : 98% H2SO4 by mass (98 G H2SO4 + 2 g water) Solution: Moles of H2SO4 = w/Molarass = 98/98 = 1 Moles of Water = 2/18 = 0.11 Mole fraction X = 1/(1+0.11) = 1/1.11 = 0.90

Calculate the mole fraction of Haso4in a solution containing 98 percent Haso4by mass.

Answer»

Answer:

0.90

Apply formula X = N/n+N

Explanation:

where X is mole fraction of H2SO4

N is number of MOLES of H2SO4

n is number of moles of water

Given : 98% H2SO4 by mass

(98 G H2SO4 + 2 g water)

Solution:

Moles of H2SO4 = w/Molarass

= 98/98

= 1

Moles of Water = 2/18

= 0.11

Mole fraction X = 1/(1+0.11)

= 1/1.11

= 0.90
