Homework Statement
Dinitrogen monoxide (nitrous oxide) N2O decomposes producing nitrogen and oxygen gases.
The atomic masses are N: 14.0 and O: 16.0
The molar volume of an ideal gas at STP is 22.4 dm3/mol
Homework Equations
Calculate the total volume of produced gases at STP, when 8.8 grams of dinitrogen monoxide decomposes?
The Attempt at a Solution
Vtotal des gaz=VN+VO
N2O -------> 2N + O
8.8g---------mN
44g/mol------14g/mol
mN=(8.8*14)/44=2.8g
nN=2.8/14=0.5mol.
22.4=VN/nN
VN=22.4*nN
VN=22.4*0.5=11.2L?
