The mass of solute per 100 mL of solution is abbreviated as (m/v). Mass is not technically the same thing as weight, but the abb

reviation (w/v) is also common. How many grams of sucrose are needed to make 715 mL of a 39.0% (w/v) sucrose solution?

Answer:

Amount of sucrose required = 278.85 g

Explanation:

(w/v)% = 39.0 %

Volume of the solution = 715 mL

39% (w/v) means 39 g of sucrose present in 100 mL of the solution.

Using unitary method,

For making 39% solution,

100 mL solution requires 39 g of the sucrose

therefore, 715 mL solution requires:

                                                715\;mL \times\frac{39\;g}{100\;mL}

                                                = 278.85 g

Imagine the reaction A + B ⇌ C + D is at equilibrium, where the forward and reverse reactions are at equal rates. What would hap
kondaur [170]

Answer:

Rate of forward reaction will increase.

Explanation:

Effect of change in reaction condition on equilibrium is explained by Le Chatelier's principle. According to this principle,

If an equilibrium condition of a dynamic reversible reaction is disturbed by changing concentration, temperature, pressure, volume, etc,  then reaction will move will in a direction which counteract the change.

In the given reaction,

A + B ⇌ C + D

If concentration of A is increase, then reaction will move in a direction which decreases the concentration of A to reestablish the equilibrium.

As concentration A decreases in forward direction, therefore, rate of forward reaction will increase.
