A flexible container at an initial volume of 6.13 L contains 8.51 mol of gas. More gas is then added to the container until it r

eaches a final volume of 18.5 L. Assuming the pressure and temperature of the gas remain constant, calculate the number of moles of gas added to the container.

Explanation:

According to Avogadro's law, equal volumes of all the gases at same temperature and pressure will also, have same number of molecules.

That is,             V \propto n

or                      \frac{V}{n} = k

Since, it is given that V_{1} is 6.13 L, n_{1} is 8.51 mol, and V_{2} is 18.5 L.

Hence, calculate the n_{2} as follows.

                        \frac{V_{1}}{n_{1}} = \frac{V_{2}}{n_{2}}

                        \frac{6.13 L}{8.51 mol} = \frac{18.5 L}{n_{2}}  

                           {n_{2}} = 0.35 mol

Thus, we can conclude that the number of moles of gas added to the container is 0.35 mol.

Write a chemical equation for nh4+(aq) showing how it is an acid or a base according to the arrhenius definition.
GuDViN [60]

An Arrhenius acid by definition dissociates in water to form H3O+ (or H+) ions while an arrhenius base dissociates in water to form OH- ions.

NH4+(aq) can be categorised as an arrhenius acid since it releases H3O+ ions in aqueous media

NH4+(aq) + H2O (aq) ↔ NH3 (aq) + H3O+(aq)
