Answer:
Find the molar mass of all the elements in the compound in grams per mole.
Find the molecular mass of the entire compound.
Divide the component's molar mass by the entire molecular mass.
You will now have a number between 0 and 1. Multiply it by 100% to get percent composition.
Explanation:
The basis for spontaneous reactions and their dependence on temperature is given by the equation for the Gibbs Free energy:
ΔG<span> = Δ</span>H<span> – </span>TΔ<span>S < 0
</span>
For a spontaneous reaction to occur, ΔG must be negative. Following the equation, ΔH must be < 0, and ΔS must be > 0 for a reaction to be spontaneous at all temperatures. However, the given values have a negative value for both enthalpy and entropy. This means that spontaneity can only occur below a certain temperature, which can be calculate by setting ΔG as zero. This gives:
ΔG = ΔH – TΔS = 0
T = ΔH/ΔS = -50/-0.3 = <span>166.67 Kelvin
</span>
Anything below that temperature gives a negative ΔG, making it spontaneous.
Answer:
<h2>2200 L</h2>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 37.4 g
density = 0.017 g/L
We have
We have the final answer as
<h3>2200 L</h3>
