Question

When 3.44 moles of butane (c4h10) react with oxygen it forms water and carbon dioxide how many molecules of carbon dioxide are formed?"

Answer 1

balanced chemical reaction is

2C4H10+13O2--> 8CO2+10H2O

2moles butane produce 8 moles of CO2

3.44 moles of butane will produce 8x3.44/2=13.76 moles= 13.76 x 6.022x10^23=82.86x10^23 molecules
