Question

A gas cylinder can hold 1 kg of hydrogen at room temperature and pressure. (a) What mass of carbon dioxide can it hold under similar conditions of temperature and pressure. (b) if the number of molecules in hydrogen of cylinder is X, calculate the number of carbon dioxide molecules in the cylinder. Give reason for your answer.

Answer 1

here temperature , pressure and volume ( cylinder) all are constant .
so , number of mole must be constant .

mole of hydrogen gas = given wt/molar wt = 1000/2 = 500 mole .

mole of carbon dioxide = given wt/molar wt
500 = given wt/44

given wt = 500×44 = 22 kg

b) here number of moles are constant
so, no of molecules also constant becoz
no of molecules = mole ×avogadro's constant

so, number of molecules of carbon dioxide are also equal to X

Answer 2

Answer:

hehehe

good question btw
