Explanation:
bends when it passes through water
Answer:
lbm/ft³ or psi/ft
Explanation:
The description in the question shows the density to measured is that of gases (upper atmosphere). The density of a gas can be described as the mass of the gas divided by the volume of the gas at a certain temperature and pressure. It's unit can be represented as lbm/ft³ or psi/ft.
NOTE:
"lbm" means "lean body mass" which is a unit for mass or weight and can be described as the pound mass
"psi" means "pound per square inch"; is also a unit for mass or weight
for liquid to gas, Evaporation or vaporization.
for gas to liquid, condensation occurs. The opposite of evaporation. Condensation is when the gas gives up it's latent heat and simply condenses.
Molality is simply defined as the number of moles of
solute over the mass of the solvent.
In this case the solute is NaCl and the solvent is water,
therefore:
moles solute = 0.630g/ 58.44 g/mol = 0.0108 mol
So the molality is:
m = 0.0108 mol / (0.525 kg)
<span>m = 0.0205 molal</span>
