Answer:
protons and neutrons
Explanation:
those particles account for 99.99% of mass
Both compare the rate of population growth.
The freezing point depression of the solution or pure substance that is added with the solvent is calculated through the equation,
ΔTf = Kfm
where ΔT is the freezing point depression, Kf is the constant for water given to be -1.86°C/m and m is the molality of the solution.
Molality is calculated through the equation,
m = number of moles solute/ kg of solvent
Calculation of molality is shown below.
m = (21.5 g C6H12O6)(1 mol/180 g) / (0.255 kg)
m = 0.468 molal
The freezing point depression is then,
ΔTf = (-1.86°C/m)(0.468 m) = -0.87°C
<em>Answer: -0.87°C</em>
Answer:
if you do not like the answer that i have presented you with on this fine day then your a smelly sea pickle.
Explanation:
Joule is a unit of work or energy. Work is calculated by multiplying the amount of force exerted with the displacement of the object. The equation would then be,
W = F x d
If we are to write the units of measurement for the given parameters, that would be
Joules = Newton x meter
Thus, the answer is newton.meter of energy. The answer is the last choice.
