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!

If a compound has a molar mass of 180 g/mol and its empirical formula is CH2O, what is its molecular formula? CH2O C2H4O2 C6H12O

irinina [24]

Its molecular formula : C₆H₁₂O₆

<h3>Further explanation </h3>

The empirical formula(EF) is the smallest comparison of atoms of compound forming elements.

A molecular formula(MF) is a formula that shows the number of atomic elements that make up a compound.

(EF) n = MF

its empirical formula is CH₂O

CH₂O : 12+2+16=30
