You determine that a sample of a compound contains 1. 4 mol c and 2. 1 mol h. What is the empirical formula for this compound?.
vlada-n [284]

The empirical formula of the compound is C4H1.

An empirical formula represents the whole number ratio of various atoms present in a compound.

If the mass percent of various elements present in a compound is known, its empirical formula can be determined

We are given that a compound contains 4 mole C and 1 mole H.

Hence, the ratio of C: H is 4:1, which is already in the form of the simplest whole number.

Therefore, the empirical formula of the given compound is C4H1 and its molecular mass is 12 x 4 + 1 = 49.

How many grams of MgCl2 (molar mass = 95.20 g/mol) will be formed from 25.6 mL of a 0.100 M HCL solution reacting with excess ma
lorasvet [3.4K]
The balanced equation for the above reaction is as follows;
Mg + 2HCl ---> MgCl₂ + H₂
stoichiometry of HCl to MgCl₂ is 2:1
we have been told that Mg is in excess therefore HCl is the limiting reactant 
number of HCl moles reacted - 0.100 mol/L x 0.0256 L = 0.00256 mol
according to molar ratio, number of MgCl₂ moles formed - 0.00256/2 
Therefore number of MgCl₂ moles formed - 0.00128 mol
mass of MgCl formed - 0.00128 mol x 95.20 g/mol = 0.122 g
