8g of CH\(_4\) occupies 11.2 at S.T.P. What volume would 22g of CH\(_3\)CH\(_2\)CH\(_3\) occupy under the same condition?
A
3.7dm\(^3\)
B
11.2dm\(^3\)
C
22.4dm\(^3\)
D
33dm\(^3\)
correct option: b
Molar mass of methane, CH4 = 16g/mol
At standard conditions, S.T.P., 8g CH4 occupies 11.2
Hence, 16g occupies 22.4 dm\(^3\)
Molar mass of propane = 44g/mol\(^-1\) occupies 22.4dm\(^3\) at S.T.P
Hence,
22g will occupy 11.2dm\(^3\)
