There are 0.5 moles of carbon, 1 mole of hydrogen, and 0.25 mol of oxygen. What is the empirical formula of this compound?

C₂H₄O

Explanation:

The empirical formula of a compound is defined as the simplest whole number ratio of the atoms present in a molecule. As we have in the molecule Carbon, Hydrogen and Oxygen to find the simplest ratio we need to divide each number of moles in the moles of Oxygen (The lower number). As follows:

C = 0.5mol C / 0.25mol O = 2

H = 1 mol H / 0.25mol O = 4

O = 0.25mol O / 0.25mol O = 1

The empirical formula is:

the leaf is an organ of a typical plant, and the main functions are to complete photosynthesis and allow the plant to exchange gas, just like how we have the respiratory system. leaves have the stomata, which collects maintains co2 and o2 levels. this is necessary for cell metabolism. the leaf also collects sunlight using chloroplasts. succinctly, leaves own a pivotal role in sustaining plant life.
