A. 0.3 moles de HCl (soluto) moles de agua (solvente)= 100 g de agua/ 18 g/mol = 5.556 mol Xsoluto = 0.3 moles = 0.35 (0.3+5.556)moles
X solvente= 0.556 moles = 0.65 (0.3+5.556)moles
X total = 0.35 + 0.65 = 1
b..01 moles de KCl moles de agua (solvente)= 1500 g de agua/ 18 g/mol = 83.33 mol Xsoluto = 0.1 moles = 0.01 (0.1 + 83.33)moles
moles de agua (solvente)= 100 g de agua/ 18 g/mol = 5.556 mol
Xsoluto = 0.3 moles = 0.35
(0.3+5.556)moles
X solvente= 0.556 moles = 0.65
(0.3+5.556)moles
X total = 0.35 + 0.65 = 1
b..01 moles de KCl
moles de agua (solvente)= 1500 g de agua/ 18 g/mol = 83.33 mol
Xsoluto = 0.1 moles = 0.01
(0.1 + 83.33)moles
X solvente= 83.33 moles = 0.99
(0.1+83.33)moles
X total = 0.01 + 0.99= 1
c. 10 g de HCl
250 g de agua
moles HCl = 10 g / 36.5 g/mol = 0.274 mol soluto
moles H₂O = 250 g / 18 g/mol = 13.888 mol solvente
X soluto = 0.274 moles = 0.019
( 0.274 + 13.888)moles
Xsolvente= 13.888 moles = 0.9806
( 0.274 + 13.888)moles
X total = 0.019 + 0.9806 = 0.9996 ≈ 1
d. 30 g de H₂SO₄ (soluto)
moles = 30 g / 98 g/mol = 0.3061 mol
800 g de agua (solvente)
moles = 800 g de agua/ 18 g/mol = 44.444 mol
Xsoluto = 0.3061 moles = 0.006
(0.3061+44,444)moles
X solvente= 44,444 moles = 0.993
(0.3061+44,444)moles
X total = 0.006 + 0.993 = 0.999 ≈ 1
