Answer:
Empirical formulas can be determined from the percent composition of a compound. In order to determine its molecular formula, it is necessary to know the molar mass of the compound. Chemists use an instrument called a mass spectrometer to determine the molar mass of compounds.
hope this helps :3
False. The principle states that the buoyant force on an object is equal to the weight of the fluid displaced by the object.
<h3>What is Archimedes' principle?</h3>
It is a theory propounded by Archimedes. It opines that a floating body is acted upon by a buoyant force.
The buoyant force is the same as the weight of the fluid displaced by the floating body.
Thus, instead of saying 'the buoyant force is equal to the blank of the fluid displaced', it is actually 'the buoyant force is equal to the weight of the fluid displaced'.

Answer:
volume of 
Explanation:
Firstly balance the given chemical equation,

From the given balance equation it is clearly that,
2 mole of Li gives 1 mole of H2 gas
⇔
⇔
⇔
hence
3 mole of Li will give 1.5 mole H2 gas
therefore volume of gas produced from 3 mole Li at 
volume of H2=33.6 litre
