Determine the moles of solute particles dissolved in 1.0 Kg of water, for the following solutions:
a) CH3CH2OH, 2.0 m; b) KCl, 2.5 m; c) Al2(SO4)3, 1.0 m; d) C12H22O11 (saccarosio), 3.0 m; e) HNO3, 2.0 m
a)
CH3CH2OH is a non-electrolyte.
"2.0\\ moles\\ of\\ particles"
b)
KCl produces 2 ions:
KCl --> K+ + Cl-
"2.5\\times2=5.0\\ moles\\ of\\ particles"
c)
Al2(SO4)3 produces 5 ions:
Al2(SO4)3 --> 2Al3+ + 3SO42-
"1.0\\times5=5.0\\ moles\\ of\\ particles"
d)
C12H22O11 is a non-electrolyte.
"3.0\\ moles\\ of\\ particles"
e)
HNO3 produces 2 ions:
HNO3 --> H+ + NO3-
"2.0\\times2=4.0\\ moles\\ of\\ particles"
