CH4 + 2O2 ----> CO2 + 2H2O
Mass of methane = 3.85 g
Mass of oxygen = 5.8 g
Molar mass of methane = 16.04 g/mol
Molar mass of oxygen = 16 g/mol
No. of moles of methane = mass/molar mass = 3.85 g/16.04 g/mol = 0.24 moles
No. of moles of oxygen = mass/molar mass = 5.8 g/16 g/mol = 0.3625 moles
Molar ratio of methane and oxygen = 1 :2
1 mole of methane require 2 moles of oxygen
0.24 mole of methane require == 0.24 x 2 = 0.48 moles of oxygen but the taken moles of oxygen is 0.3625
Hence oxygen is the limiting reactant
Molar ratio of oxygen and carbon dioxide = 2:1
moles of carbon dioxide = 0.5 x 0.3625 moles = 0.18125 moles
Molar mass of carbon dioxide = 44.01 g/mol
Maximum mass of carbon dioxide = moles x molar mass = 0.18125 mol x 44.01 g/mol = 7.98 g = 8.0 g (2 significant figures)
