This question is based on Dalton's Law of Partial Pressure which states that "the total pressure of a system of gas is equal to the sum of the pressure of each individual gas (partial pressure).
Now, Partial Pressure of a gas = (mole fraction) × (total pressure)
⇒ Partial Pressure of Hydrogen =
× 
= 0.31 atm
Thus the Partial Pressure of Hydrogen in the container is 0.31 atm.
Now, Partial Pressure of a gas = (mole fraction) × (total pressure)
⇒ Partial Pressure of Hydrogen =
= 0.31 atm
Thus the Partial Pressure of Hydrogen in the container is 0.31 atm.
First, we need to find the atomic mass of 
.
According to the periodic table:
The atomic mass of Carbon = C = 12.01
The atomic mass of Hydrogen = H = 1.008
The atomic mass of Oxygen = O = 16
As there are 6 Carbons, 12 Hydrogens and 6 Oxygens, therefore:
The molar mass of = 6 * 12.01 + 12 * 1.008 + 6 * 16
The molar mass of = 180.156 grams/mole
Now that we have the molar mass of, we can find the grams of glucose by using:
mass(of glucose in grams) = moles(of glucose given in moles) * molar mass(in grams/mole)
Therefore,
mass(of glucose in grams) = 2.47 * 180.156
mass(of glucose in grams = 444.99 grams
Ans: Mass of glucose in grams in 2.47 moles = 444.99 grams
