Yesn’t. they are either wrong or links
Answer:
just guessing, but hydrolisis indicates ; hydro= h2o. lisis= destruction.
Explanation:
in my training, this wud mean destruction of water, or loss of water in the human body.
2 equalibrate, takes sodium chloride, to retain fluids by IV.
Hey there!:
ΔTf = Kf * m
Molar mass glucose = 180 g/mol
number of moles glucose:
n = mass of solute / molar mass
n = 21.5 / 180
n = 0.119 moles glucose
Amount of solvent in kg = 255/1000 = 0.255 Kg
Molality = number of moles / solvent
m = 0.119 / 0.255
m = 0.466 moles/kg
Kf for water = - 1.86 ºC/*m
Therefore:
ΔTf = Kf * m
ΔTf = (-1,86) * 0.466
ΔTf = -0.86676 ºC
hope this helps!
Answer:
1.818x10²³ particles
Explanation:
Add the two atomic masses given to get 74.55 g.
Divide the number of grams given by the molar mass of KCl:
22.5g ÷ 74.55 = 0.302 mol
Multiply the moles by 6.022×10²³ particles
