A gaseous mixture contains 60% nitrogen , 15% oxygen and 25% carbon dioxide by mass . Calculate the mole fraction of each gas . plzz answer fasttttttt .................. plzzzzzzzzzzzzzzz
Molar mass of nitrogen gas = 28 g
Molar mass of oxygen gas = 32 g
Molar mass of carbon dioxide gas = 44 g
Given mass of nitrogen = 60 g
Given mass of oxygen = 15 g
Given mass of carbon dioxide = 25 g
Number of moles (n) =
= 2.1428 moles
= 0.468 moles
= 0.568 moles
Total number of moles = 2.1428 + 0.468 + 0.568 = 3.1788 moles
Mole fraction of N2 =
Mole fraction of O2 =
Mole fraction of CO2 =
Molar mass of oxygen gas = 32 g
Molar mass of carbon dioxide gas = 44 g
Given mass of nitrogen = 60 g
Given mass of oxygen = 15 g
Given mass of carbon dioxide = 25 g
Number of moles (n) =
= 2.1428 moles
= 0.468 moles
= 0.568 moles
Total number of moles = 2.1428 + 0.468 + 0.568 = 3.1788 moles
Mole fraction of N2 =
Mole fraction of O2 =
Mole fraction of CO2 =
