a compound has a molar mass of 129 g/mol if its empirical formula is C2H5N then what is the molecular formula
Elena-2011 [213]

Given :

A compound has a molar mass of 129 g/mol .

Empirical formula of compound is C₂H₅N .

To Find :

The molecular formula of the compound.

Solution :

Empirical mass of compound :

M_e = ( 2 \times 12 ) + ( 5 \times 1 ) + (  1  \times 14 )\\\\M_e = 43\ gram/mol

Now, n-factor is :

n = \dfrac{M}{M_e}\\\\n = \dfrac{129}{43}\\\\n = 3

Multiplying each atom in the formula by 3 , we get :

Molecular Formula, C₆H₁₅N₃

Calculate the mass (in grams) of 0.473 mol of titanium
xz_007 [3.2K]

Explanation:

n=given mass ÷molar mass

make given mass become the subject of the formula by

multiplying the molar mass on both sides of the equation.

n=0.473mol

given mass=??

molar mass=48

therefore,given mass=n×molar mass

=0.473×48

=22.704grams

mass in grams is 22.704grams

meriva

The metal is sodium, Na.

<u>Explanation:</u>

K₂O is an ionic compound in which K is in the oxidation state of +1 and it belongs to group 1.

Group 1 elements also form oxides with the metals with the general formula M₂O and M being Na, K, Li and so on.

Metals Like sodium and Potassium are so brittle in nature and also their oxides.

So the other metal that form metal oxide which is brittle as well as ionic in nature, and so the metal oxide is Na₂O.

So the metal is sodium, Na.
