How many moles of ammonium ions are in 0.557 grams of ammonium carbonate uses?

Chemistry

kompoz [17]3 years ago

The chemical formula for ammonium carbonate is (NH₄)₂CO₃ .  

It shows that one mole of ammonium carboonate contains two mole of ammonium ion that is NH₄⁺ .

Number of moles of ammonium carbonate , n=  

\frac{Given mass of ammonium carbonate}{Molar mass of the ammonium carbonate}

Given mass of the ammonium carbonate=0.557 g

Molar mass of the ammonium carbonate=  96.086 g/mol

Number of moles of ammonium carbonate,  

n= \frac{ 0.557 }{96.086}

      =0.0057 mol (NH₄)₂CO₃

0.0057 mol (NH₄)₂CO₃=0.0057×2 of NH₄⁺

                                  =0.0114 of NH₄⁺

Select the appropriate words to fill in the blanks. A solution in which no more solute can be dissolved in is referred to as ___
Temka [501]

Answer:

A solution in which no more solute can be dissolved in is referred to as SATURATED. In such a solution, the concentration of solute is called SOLUBILITY . When that concentration is reported in moles per liter, it is more specifically called MOLAR SOLUBILITY. A special equilibrium constant called the SOLUBILITY PRODUCT constant is calculated from the molar concentrations of the aqueous components of the dissolution equation.

Explanation:

The solubility of a solute in a solvent is the maximum amount of solute in moles that will be dissolved in 1dm3 of the solvent at a specified temperature. Once the maximum number or concentration has been reached, the solvent can no longer take in solutes and this point in the reaction, the solution is said to be saturated. That is the composition of the saturated solution is not affected by the presence of excess solute. An unsaturated solution has a lower concentration of solute and can dissolve more solutes if added until it becomes saturated.

Solubility when reported in moles per liter is called molar solubility of the solution and it gives a more accurate measurement of yh solubility of a solution. The solubility product constant is calculated from the molar concentrations of the aqueous components of the dissolution equation. This solubility product constant explains the balance between dissolved ions from the salt and undissolved salt in a dissolution equation.

Serhud [2]

Answer:

The water cycle, also known as the hydrologic cycle or the hydrological cycle, describes the continuous movement of water on, above and below the surface of the Earth. The mass of water on Earth remains fairly constant over time but the partitioning of the water into the major reservoirs of ice, fresh water, saline water and atmospheric water is variable depending on a wide range of climatic variables. The water moves from one reservoir to another, such as from river to ocean, or from the ocean to the atmosphere, by the physical processes of evaporation, condensation, precipitation, infiltration, surface runoff, and subsurface flow. In doing so, the water goes through different forms: liquid, solid (ice) and vapor. Hope this helps, mark as brainliest please!
