The volume occupied by 11.5 g of carbon dioxide at STP is approximatel

1.	The volume occupied by 11.5 g of carbon dioxide at STP is approximately equal to: (A) 5.9 L (B) 22.5 L (C) 86 L (D) 259 L
Answer» Correct option is: (A) 5.9 L Molecular weight of \(CO_2\) = 44g/mol Number of moles\(CO_2\) = \(\frac {11.5}{44}mol\) = 0.26 mol Using ideal gas equation PV = nRT V = \(\frac {0.26\times 0.082\times 273}{1\, atm}\) V = 5.82 L Correct option is (A) 5.9 L

The volume occupied by 11.5 g of carbon dioxide at STP is approximately equal to: (A) 5.9 L (B) 22.5 L (C) 86 L (D) 259 L

Answer»

Correct option is: (A) 5.9 L

Molecular weight of \(CO_2\) = 44g/mol

Number of moles\(CO_2\) = \(\frac {11.5}{44}mol\)

= 0.26 mol

Using ideal gas equation

PV = nRT

V = \(\frac {0.26\times 0.082\times 273}{1\, atm}\)

V = 5.82 L

Correct option is (A) 5.9 L
