Answer:
A.
Explanation:
The sun unevenly hits the Earth, causing wind to form and move around the poles; never constant.
In science, we have a name for this, called Avogadro's number, and it describes the number of representative particles in one mole of a substance. The inverse mole unit tells us there are 6.022×1023 particles of something *per mole* so there are 1,023 particles
The boiling point in ethanol is much higher than hexane due to ethanol having stronger hydrogen bond present compared to hexane. Therefore the ethanol requires more energy to break the bonds, having a higher boiling point.
Answer:
The weight/weight % or percent by mass of the solute is 1.04g.mL
Explanation:
We assume, (i) that the solvent is water, and (ii) that dissolution occurs without change in volume.
So given the standard density of water, the mass of the solution is simply,
(4.87+86.4)g
For solution,
=
= 1.04 g. mL
Because nitrate salts are soluble stuff, you could get significantly higher solution densities if you dissolved more salt (volume change would be fairly negligible).
