A 25.00 mL sample of the ammonia solution
musickatia [10]

Answer:

1.634 molL-1

Explanation:

The mol ration between NH3 and HCl is 1 : 1

Using Ca Va / Cb Vb = Na / Nb   where a = acid and b = base

Na = 1

Nb = 1

Ca = 0.208 molL-1

Cb = ?

Va = 19.64 mL

Vb = 25.00mL

Solving for Cb

Cb = Ca Va / Vb

Cb = 0.208 * 19.64 / 25.0

Cb = 0.1634 molL-1 (Concentration of diluted ammonia solution)

Using the dilution equation;

C1V1 = C2V2

Initial Concentration, C1 = ?

Initial Volume, V1 = 25.00 mL

Final Volume, V2 =  250 mL

Final Concentration, C2 = 0.1634 molL-1

Solving for C1;

C1 = C2 * V2 / V1

C1 = 0.1634 * 250 / 25.00

C1 = 1.634 molL-1

Determine the empirical formula of a compound containing 22.6% nitrogen and 77.4% oxygen
Leona [35]
The empirical  formula  of a compound that  contain 22.6%  nitrogen and 77.4% oxygen  is calculated as below

calculate the moles of each element
= % composition/molar mass
that is
         N(nitrogen) = 22.6/14= 1.61 moles
         O(oxygen)  = 77.4/16 = 4.84  mole

find the mole ratio by dividing each mole  by the  smallest  mole ( 1.61 moles)

that is 
        N = 1.61/1.61 = 1 
        O = 4.84/1.61 = 3

therefore the empirical  formula = NO3
