<span>She must use Avogadro's Number. Avogadro's number is the number of molecules in a mole of a substance, so if you have 12.4 moles of something, then you have 12.4 times Avogadro's number of molecules.</span>
The correct choices are: (2) the particles in the Warner cup has more kinetic energy and (3) if there are two different amounts of the same liquid the temp is a good way to compare thermal energies
Explanation:
In order to calculate the number of moles of a compound, we will find it out as follows.
No. of moles of chromium(III) chloride =
=
= 0.63 moles
No. of moles of =
=
= 5.88 moles
No. of moles of =
=
= 1.05 moles
No. of moles of =
=
= 1.02 moles
No. of moles of KCl =
=
= 1.34 moles
No. of moles of =
=
= 1.31 moles
No. of moles of =
=
= 6.25 moles
No. of moles of =
=
= 2.27 moles
No. of moles of =
=
= 1.11 moles
Therefore, we can conclude that out of the given options contains the largest number of moles of compound.
Answer: 240 mL
Explanation:
(20 kPa)(300 mL) = (25 kPa)V2
V2 = 240 mL
Or my way which was
300 mL / 25 kPa =12
12(5)=60
300-60=240mL
