Question

9.
Two identical vessels are filled with 44g of
hydrogen and 44g of carbon dioxide at the same
temperature. If the pressure of Co, is 2 atm, the
pressure of hydrogen is
1) 1 atm 2) 44 atm 3) 2 atm 4) 22 atm​

Answer 1

The pressure of hydrogen is equal to 44 atm.

• 44 g of hydrogen contains 22 moles of hydrogen while 44 g of carbon dioxide contains 1 mole of carbon dioxide.
• The pressure of the gas is directly proportional to the number of moles of the gas (PV=nRT).
• As one mole of carbon dioxide gas is equivalent to 2 atm pressure, 22 moles of hydrogen gas will have (2×22) 44 atm pressure.

Answer 2

Answer:

44g of CO2 = 1 mol

44g of CO2 = 1 mol p = 2 atm

44g of CO2 = 1 mol p = 2 atm 44 g of H2 = 44\ 2 = 22 mol

44g of CO2 = 1 mol p = 2 atm 44 g of H2 = 44\ 2 = 22 mol = 22 x 2atm pressure

44g of CO2 = 1 mol p = 2 atm 44 g of H2 = 44\ 2 = 22 mol = 22 x 2atm pressure pressure of H2 = 44 atm
