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.
Answer:
There are
grams contained in all the seawater in the world.
Explanation:
At first let is determinate the total mass of seawater (
), measured in grams, in the world by definition of density and considering that mass is distributed uniformly:

Where:
- Density of seawater, measured in grams per liters.
- Volume of seawater, measured in liters.
If
and
, then:


The total mass of sodium chloride is determined by the following ratio:


Given that
and
, the total mass of sodium chloride in all the seawater in the world is:

There are
grams contained in all the seawater in the world.
