which information must be known about a compound to find the molecular formula from the empirical formula?\no density\no formula mass\no percent composition\no mole ratio
Answer
Brief Explanations:
To get the molecular formula from the empirical formula, we need to know the ratio of the formula mass of the molecular formula to the formula mass of the empirical formula. This ratio is an integer multiple that scales the empirical - formula to the molecular formula. Density, percent composition, and mole ratio are not directly used to convert from empirical to molecular formula.
Answer:
formula mass
