-answer the first question before touching any buttons- 1. if you already have the mass (in g) of your elements, press "edit element masses" and skip to "g to mol" 2. input percentages as numbers only, no % sign 3. put mass measurements in grams, and again NO SIGNS (don't write "g") 4. if your coefficients for empirical and/or molecular formula can't be rounded within ~0.1 to a whole number, but they are close to 0.25 or 0.33 or whatever, just multiply the coefficients by the same # to make them whole. coefficients of your empirical formula are the empcoeffs. of your molecular formula they are molcoeffs. do some healthy rounding
i couldn't be bothered to include all the molar masses so you'll have to do that yourself but here u guys go!
