What is the empirical formula of a The empirical formula shows the simplest whole
compound? number ratio of atoms of each element in the
compound.
What is the molecular formula of a The molecular formula shows the actual numbers of
compound? atoms of each element in a molecule.
,How do you calculate the empirical Calculate the amount of each element, convert to
formula from mass data? moles, and find the simplest whole number ratio.
What is the molar gas volume at 1 mole of any gas occupies 24 dm³ (24000 cm³) at
room temperature and pressure? room temperature and pressure.
How do you calculate the number of Moles = volume of gas (dm³) / 24.
moles from gas volume?
What is the formula to calculate % Yield = (actual yield / theoretical yield) x 100.
percentage yield?
,What is atom economy? Atom economy measures the efficiency of a
reaction in terms of the amount of starting materials
that become useful products.
What is the relationship between When gases react, the volumes consumed and
reacting gas volumes according to produced are in ratios of small whole numbers.
Gay-Lussac's Law?
How do you determine the empirical Convert percentage composition to grams,
formula from percentage calculate moles, and find the simplest ratio.
composition?
, What is Avogadro's Law? Avogadro's Law states that equal volumes of gases
at the same temperature and pressure contain the
same number of molecules.
What is the empirical formula of a The empirical formula is NaNO3.
compound with 4.6 g Na, 2.8 g N,
and 9.6 g O?
How do you find the molecular Calculate the empirical formula mass and divide the
formula from the empirical formula? given RFM by it to find the multiplier for the
