Question

What volume of oxygen is required to completely burn a mixture of 224 cm³ of methane and 112 cm³ of hydrogen at STP to produce steam and carbon dioxide? If the steam is condensed to
water , find mass of water formed?

Answer 1

therefore, 112cm cube of hydrogen will require 56cm cube of oxygen for complete combustion and thereby form 112 cm cube of steam. therefore, total volume of oxygen needed 4 burning CH4 a4H2 = 448+56=504 cm cube and total volume of steam formed =448+112=560 cm cube.
