As water is added to a 0.10 M NaCl aqueous solution, the conductivity of the resulting solution

Chemistry

There are two types of conductance

a) molar conductance

b) specific conductance

specific conductance is also known as conductivity

Molar conductance [the conductance offered by one mole of electrolyte dissolved in any volume of solution] increases with increase in dilution. The reason for weak and strong electrolytes are different.

i) for weak electrolytes the molar conductance increases due to increase in degree of dissociation

ii) for strong electrolytes the molar conductance increases due to decrease in inter ionic interactions

Conductivity (specific conductance) is the conductance offered by one unit volume of an electrolytic solution

The conductivity decreases with increase in dilution due to less number of ions per unit volume of solution.

so here the conductivity of resulting solution will decrease if water is added to a 0.10 M NaCl  solution

The more water added the lower the conductivity. The Na+ and Cl- ions allow the solution to be conductive. The lower the concentration, the less conductive the solution will get until it is not conductive at all.

Assuming an efficiency of 30.80%, calculate the actual yield of magnesium nitrate formed from 147.4g of magnesium and excess cop
Reil [10]

Answer:

The answer to your question is 280 g of Mg(NO₃)₂

Explanation:

Data

Efficiency = 30.80 %

Mg(NO₃)₂ = ?

Magnesium = 147.4 g

Copper (II) nitrate = excess

Balanced Reaction

                     Mg  +   Cu(NO₃)₂    ⇒    Mg(NO₃)₂   +   Cu

                  Reactants           Elements            Products

                         1                          Mg                     1

                         1                          Cu                      1

                         2                          N                       2

                         6                          O                       6

Process

1.- Calculate the theoretical yield

Molecular weight Mg = 24

Molecular weight Mg(NO₃)₂ = 24 + (14 x 2) + (16 x 6)

                                              = 24 + 28 + 96

                                              = 148 g

                           24 g of Mg  --------------------  148 g of Mg(NO₃)₂

                          147.4 g of Mg -------------------   x

                            x = (147.4 x 148) / 24

                            x = 908.96 g of Mg(NO₃)₂

2.- Calculate the Actual yield

yield percent = \frac{actual yield}{theoretical yield}

Solve for actual yield

Actual yield = Yield percent x Theoretical yield

Substitution

Actual yield = \frac{30.8}{100} x 908.96

Actual yield = 279.95 ≈ 280g
