Question

In a 1.0× 10–2 M solution of NH4ClO4(aq), identify the relative molar amounts of these species.

Answer 1

In a 1.0× 10–2 M solution of NH4ClO4(aq), the relative molar amounts of NH4+ and ClO4- are both 1.0×10–2 M.

Step-by-step explanation:

In a 1.0× 10–2 M solution of NH4ClO4(aq), there are different species present. Let's identify their relative molar amounts.

The dissociation of NH4ClO4 in water is as follows:

NH4ClO4(aq) → NH4+(aq) + ClO4-(aq)

Since the molarity of the solution is 1.0× 10–2 M, the relative molar amounts of NH4+ and ClO4- are both 1.0× 10–2 M.

Answer 2

Given: NH4ClO4 aqueous solution

Concentration of the solution: 1.0 x 10^-2 mol/L

Assuming: 1 Liter solution

Number of moles of NH4ClO4 = 1.0 x 10^-2 moles

Relative molar amounts:

N: 1/1.0 x 10^-2 = 100
H: 4/1.0 x 10^-2 = 400
Cl: 1/1.0 x 10^-2 = 100
O: 4/1.0 x 10^-2 = 400
