26.8 g Na2SO4.nH2O has 12.6 g water. Find the value of n.
Asked by Anil | 15th May, 2017, 12:33: PM
Expert Answer:
Na2SO4 x n H2O
Molar mass of salt = (142 + 18n)
Mass of water = 12.6/26.8 x (142 + 18n)
18 n = 12.6/26.8 (142 + 18n)
n = 7
Na2SO4 x n H2O
Molar mass of salt = (142 + 18n)
Mass of water = 12.6/26.8 x (142 + 18n)
18 n = 12.6/26.8 (142 + 18n)
n = 7
