Answer:
runoff
Explanation:
...............................
Kf = 1.86
Number of moles :
Molar mass <span> ethylene glycol = 62.0 g/mol
40.0 / 62.0 => 0.645 moles
Molality :
mass of solvent = 60.0 / 1000 => 0.06 kg
m = moles / kg solvent
m = </span><span>0.645 / 0.06
= 10.75 m
</span>Δt = Kf x molality
Δt = (- 1.86) x 10.75 => - 20.1ºC
<span>
Answer A

Answer:
heat capacity: "the number of heat units needed to raise the temperature of a body by one degree."
Explanation:
The formula for determination of atomic mass given the mass of isotopes and relative abundance is:
Ar = ∑(mass * abundance) / 100
Ar = (68.92558 * 60.108 + 70.92470 * 39.892) / 100
Ar = 69.72306
The atomic mass of gallium is 69.72306 amu
