We’re being asked to determine the empirical formula of a compound composed of C, H, and O, given the mass percent of C and O.
Recall that the empirical formula is the simplest whole-number ratio formula of a compound.
For this problem, we need to do the following steps:
Step 1: Calculate the moles of C, and O in the compound.
Step 2: Determine the lowest whole number ratio of C, and O to get the empirical formula.
In addition to carbon monoxide CO and carbon dioxide CO2, there is a third compound of carbon and oxygen called carbon suboxide. If a 2.500 g sample of carbon suboxide contains 1.32 g of C and 1.18 g of O, what is a possible formula for carbon suboxide?
