WebJul 21, 2024 · Notice that the carbon and oxygen mole numbers are the same, so you know the ratio of these two elements is 1:1 within the compound. Next, divide all the mole numbers by the smallest among them, which is 3.33. This division yields. The compound has the empirical formula CH2O. The actual number of atoms within each particle of … WebWhat is the empirical formula of a compound composed of 27.9 g potassium (K) and 5.71 g oxygen (O)? Solution: The chemical formula of compound is K x O y. : =𝜗(𝐾):𝜗(𝑂)= 𝑚(𝐾) 𝑀(𝐾): 𝑚(𝑂) 𝑀(𝑂) = t y.9 9: w. y s s x = r. y s w: r. u w y= t: s Thus the empirical formula of a compound is K 2 O. fox news elisabeth hasselbeck
