Question

An unknown compound contains only carbon, hydrogen, and oxygen (CxHxOx). Combustion of 3.50G of this compound produced 5.13G of carbon dioxide and 2.10G of water

A.How many moles of carbon, , were in the original sample?


b. How many moles of hydrogen, , were in the original sample?

Answer 1

i got for A) 0.117 mol

Answer 2

5.13 g CO2 x (1 mol CO2/44g) x (1 mol C/1 mol CO2) = ? and I don't believe that is 0.117

2.10g H2O x (1 mol H2O/18) x (2 mol H/1 mol H2O) = ?

Answer 3

thank you
