Answer: The molar mass of each gas
Explanation:
Mole fraction is the ratio of moles of that component to the total moles of solution. Moles of solute is the ratio of given mass to the molar mass.
Suppose if there are three gases A, B and C.
a)
b)
c)
moles of solute =
Thus if mass of each gas is known , we must know the molar mass of each gas to know the moles of each gas.
Increases the volume of water
Explanation:
Freezing of water causes the volume of water to increase by a whooping 4%. This is why the density of water is slightly different that of ice.
When ice freezes it expands and takes up more volume of space for the same mass given.
This is why bottles break when water in them is frozen.
This increase in volume is why ice floats on water. It makes it less dense.

Answer:
<h2>4. Na+ diffusing toward the side of the membrane with Cl− and 50% less Na+.</h2>
Explanation:
Facilitated diffusion is a type of transport mechanism in which the special proteins are involved and play an important role in the transport of the atoms, ions or molecules. This mechanism is based on the electrochemical gradient differences. When this difference increase, then the transport of the sodium takes place because sodium ions are chemically attracted by chloride ions. In a facilitated diffusion process, no energy requirement takes place. This process occurs along the concentration gradient.
The answer is C) Nuclear.
The answer is C because, Renewable resources are something that can be re-used over and over again. Then Nonrenewable resources can't be made right away once it's been used. That being said, the answer is C.
A) Geothermal can be reused, which makes it renewable.
B) Solar can also be reused, which makes it renewable.
C) Nuclear can NOT be reused, which makes it nonrenewable.
D) Biomas is indeed renewable.
