We are given the equation to use which is:
ΔG = ΔH - TΔS

We are also given that:
ΔG = 173.3 kJ
T = 303 degrees kelvin
ΔH = 180.7 kJ

Substitute with these givens in the above equation to get ΔS as follows:
ΔG = ΔH - TΔS
173.3 = 180.7 - 303ΔS
303ΔS = 180.7 - 173.3 
303ΔS = 7.4
ΔS = 7.4 / 303 = 0.02442 kJ/K which is equivalent to 24.42 J/k

Based on the above calculations, the correct choice is:
D. 24.42 J/K

How many molecules of hypothetical substance b are produced when 29.9g of hypothetical substance a reacts? the molar mass of sub
Andrej [43]
<span>1.15x10^24 molecules of hypothetical substance b Making the assumption that each molecule in hypothetical substance a reacts to produce a single molecule of hypothetical substance b, then the number of molecules of substance b will be the number of moles of substance a multiplied by avogadro's number. So Moles hypothetical substance a = 29.9 g / 15.7 g/mol = 1.904458599 moles This means that we should also have 1.904458599 moles of hypothetical substance b. And to get the number of atoms, multiply by 6.0221409x10^23, so: 1.904458599 * 6.0221409x10^23 = 1.146892x10^24 molecules. Rounding to 3 significant figures gives 1.15x10^24</span>
