Based on the concentration of the solutions, the increase in volume is as follows:

Osmosis is the movement of water molecules from a region of low solute concentration to a region of high solute concentration through a semipermeable membrane.

The movement of water molecules in the solution pairs is as follows:

Therefore, the increase in volume depends on the concentration ofvthe solutions.

Explanation:

cuz u have number of moles of silver which = 0.085

so u must know that molar mass of silver =107.87 g/mol

so the mass of silver = number of moles × molar mass =0.085×107.87= 9.16895 grams

The number of moles of methane gas occupies in the given volume and pressure is 1.426 moles. It can be calculated using ideal gas law.

Ideal gas law relates the parameters temperature, pressure, volume and number of moles of  a gas by the equation given below:

PV = nRT.

Where, R is the universal gas constant equal to 0.082 L atm /(K .mol). This law is a combination of Boyle's law, Charles's law and Avogadro's law.

It is given that the pressure and volume of the gas is 1.28 atm and 27.6 liter respectively. Temperature is 29 degree celsius or 302 kelvin. Using these values the number of moles of methane gas is calculated as follows:

PV = nRT

n = PV/RT

Number of moles of methane n = (1.28 atm × 27.6 L) / ( 0.082 L atm /(K .mol) × 302 K )

= 1.426 moles.

Hence, the number of moles of methane gas in the given system is 1.426 moles.

The concentration of the solution reduces and the number of moles of solute isn't affected.

Data;

1. When the solution is diluted, the concentration changes and this time, the concentration reduces.

Using dilution formula

[tex]c_1 v_1 = c_2 v_2\\12 * 50 = c_2 * 200\\c_2 = \frac{600}{200} \\c_2 = 3M[/tex]

The concentration of the solution reduces.

2. The number of moles remains the same.

When a solution is diluted, the number of moles remains the same because there's no change in the mass of the solute.

The volume of the balloon is approximately 2652 liters.

Let suppose that flammable hydrogen behaves ideally. GIven the molar mass ([tex]M[/tex]), in kilograms per kilomole, and mass of the gas ([tex]m[/tex]), in kilograms. The volume occupied by the gas ([tex]V[/tex]), in cubic centimeters, is found by the equation of state for ideal gases:

[tex]V = \frac{m\cdot R_{u}\cdot T}{P\cdot M}[/tex]   (1)

Where:

If we know that [tex]m = 0.239\,kg[/tex], [tex]R_{u} = 8.314\,\frac{kPa\cdot m^{3}}{kmol\cdot K}[/tex], [tex]T = 273.15\,K[/tex], [tex]P = 101.325\,kPa[/tex] and [tex]M = 2.02\,\frac{kg}{kmol}[/tex], then the volume of the balloon is:

[tex]V = \frac{(0.239\,kg)\cdot \left(8.314\,\frac{kPa\cdot m^{3}}{kmol\cdot K} \right)\cdot (273.15\,K)}{\left(101.325\,kPa\right)\cdot \left(2.02\,\frac{kg}{kmol} \right)}[/tex]

[tex]V = 2.652\,m^{3}[/tex] ([tex]2652\,L[/tex])

The volume of the balloon is approximately 2652 liters. [tex]\blacksquare[/tex]

The limiting reactant would be the ammonium sulfide and the amount of the excess manganese (IV) fluoride would be 1.96 grams

From the equation of the reaction:

[tex]MnF_4(aq)+2(NH_4)_2S(aq)- > MnS_2(s)+4NH_4F(aq)[/tex]

The mole ratio of [tex]MnF_4[/tex] to [tex](NH_4)_2S[/tex] is 1:2

Mole of 70 g [tex]MnF_4[/tex] = 70/130.93

                                 = 0.53 moles

Mole of 70 g  [tex](NH_4)_2S[/tex] = 70/68.154

                                       = 1.03 moles

Equivalent mole of   [tex](NH_4)_2S[/tex] = 0.53 x 2

                                                = 1.06 moles

Thus,   [tex](NH_4)_2S[/tex] seems to be limiting while [tex]MnF_4[/tex] is in excess.

Excess [tex]MnF_4[/tex] = 0.53 - 1.03/2

                          = 0.015 mole

Mass of 0.015 mole [tex]MnF_4[/tex] = 0.015 x 130.93

                                             = 1.96 grams
