A dry cleaning solvent (molar mass = 146.99 g/mol) is a compound containing C, H &amp; Cl is suspected to be a cancer causing ag
poizon [28]

Answer:

Okay so set up an equation for what's happening

_C + _H + _Cl + O2 --> _CO2 + _H2O

0.451g of CO2. Convert to moles by using the molar mass of CO2 which is 44 g/mol. Now look at the ratio between Carbon and Oxygen in CO2. It's 1C:2O You just want to find C.. so do the number of moles CO2 and multiply it by 1 since the ratio says 1 carbon atom. Now you have moles of carbon. Put this number aside for later.

Do the same thing with H2O. Convert to moles by using the molar mass of H2O which is 18 g/mol. Now look at the ratio between Hydrogen and Oxygen. It's 2H:1O You just want H.. so do the number of moles of H2O and multiply it by 2 since there's 2 hydrogen atoms. Now you have the moles of hydrogen & put this number aside for later

Lastly, you need to find the chlorine. uuhhh I cant figure this part out

Explanation: ..

I hope I helped lol!
