How do you check if the empirical formula is correct?

WebStep 4: The molecular formula equals the empirical formula multiplied by the multiplier. The molecular formula = (CH) × 8 = C8H8. Remember, when using this method you can only find the molecular formula of a compound and not its structural arrangement—that is, whether the compound is linear or cyclic. WebWe multiply the moles by the molecular weight to find the mass of glutamate. Let’s approximate 147 as 150, and to calculate (150 x 2.5), split it up into (150 x 2) and (150 x 0.5) to get 375. We then multiply 375 by 10 ^- − ^2 2 to get the mass, which is 3.75 grams. megh inc
