1.A compound with a mass of 1.083g contains only carbon and sulfur. It is burned in oxygen. The mass of CO2 obtained after burning is 0.627g. What is the simplest formula of the compound? 
Pleaseeee HELPP!

anonymous · Answer

Use this reaction which describes the combustion.

CS + O2 --> CO2 +  (SO)x. 

use the weight of CO2 to calculate the mass of C that produced it. Then use the difference in mass to obtain the weight of sulfur

Convert both C and S to moles, and find the ratio that describes it.

Answer should be something like CS2

weight of co2?

anonymous · Answer

do you mean like the atomic mass?

anonymous · Answer

The mass of CO2 obtained after burning is 0.627g

anonymous · Answer

$$0.627 g CO2 * (1 mole CO2)/(44g CO2) = X moles of CO2$$

anonymous · Answer

or you can use % compositions where 12/44*100 is the precent C in CO2

anonymous · Answer

i got the moles of co2, now what? sorry im kind of an idiot with thi s question in particular
