What information is needed to determine a molecular formula? a the empirical formula and the molarity of the solution b the empirical formula and the molar mass c the empirical formula and the percent composition d the empirical formula and the empirical formula mass

The boiling point of propanoic acid is higher than that of 1-butanol because: propanoic acid has a higher molecular weight than 1-butanol. propanoic acid is more soluble in water than 1-butanol. propanoic acid is a better hydrogen bond donor than 1-butanol. propanoic acid forms hydrogen bonded dimers and 1-butanol does not. 1-butanol forms hydrogen bonded dimers and propanoic acid does not.

Which of these conditions most likely produces an unstable isotope?

What is the independent variable in this investigation? mass volume sample number substance density
