Question

Study the scenario and balanced equation. While a Bunsen burner is ignited, 7.45 x 1024 mol of methane (CHA) react with an excess of oxygen (O2). CH2(g) + 2O2(g) + CO2(g) + 2H2O(g) (MH20 = 18.0 g/mol; MCH4 = 16.0 g/mol) What is the theoretical yield of water produced? 4.14 x 1023 g H20 2.68 x 1026 g H2O 4.14 x 1023 mol H2O 2.68 x 1026 mol H2O

Answer 1

H₂o produced by let cxxl be the 7.45 X 10 24 moles mass of of Chy. I mole of Chy gives + 2x189 of H₂o. 7.458 10 24 moles of CHy gives - x cross multiply x = 218 x 7.45X 10249 x= 2.682 x 10 26 g of H₂
