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.
The ratio of mole number of the reactants and products is equal to the coefficients. So the answer is a. 18.75 mol. b. 35.1 g. c. 1.38 * 10^5 g.
It’s C
Cooling a liquid til it freezes will cause a liquid to turn into a solid
