What will be pressure exerted by a mixture of 3.2 g of methane and 4.4 g of carbon dioxide contained in a 9 dm 3 flask at 27 ° C ?
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(8.32 × 10 4 Pa.)
Molar mass of methane (CH 4 ) = 12 + 4 × 1 = 16 g mol –1
Mass of carbon dioxide (CO 2 ) = 12 + 2 × 16 = 44 g mol –1 Moles of CH 4 = 
= 0.2 ; Moles of CO 2 = 
= 0.1
pCH 4 = 
= 
= 
= 0.554 × 10
5 Nm –2 = 5.54 10 4 Pa
pCO 2 = 
= 
= 2.77 × 10 4 Pa
Total pressure of mixture = pCH 4 + pCO 2 = (5.54 + 2.77)10 4 + Pa = 8.32 × 10 4 Pa.
