Ionic compounds that are already in its formula because it's already in its lowest ratio when we bring two ions together its actually in its lowest ration already so ionic compounds don't have an empirical molecular formula. Step 2: since you have assumed that the mass of the compound is 100g, you just rewrite the values that were given in percentages but the units are now grams (do not get confused, you just calculate the mass of the atoms by multiplying the mass of the sample by the given percentage and then dividing by 100; since the mass is assumed to be 100g, there is no point in multiplying by 100 and then dividing by 100; that is why you leave the percentage values as they are; you just change the units).
