If 91.9 mL of silver nitrate solution reacts with excess potassium chloride solution to yield 0.684 g of precipitate, what is the molarity of silver ion in the original solution?

0.052M

Explanation:

We'll begin by writing the balanced equation for the reaction. This is given below:

AgNO3(aq) + KCl(aq) → AgCl(s) + KNO3 (aq)

Next, we shall determine the number of mole present in 0.684 g of precipitate, AgCl. This is illustrated below:

Mass of AgCl = 0.684g

Molar mass of AgCl = 108 + 35.5 = 143.5g/mol

Number of mole of AgCl =.?

Mole = Mass /Molar Mass

Number of mole of AgCl = 0.684/143.5

Number of mole of AgCl = 4.77×10¯³ mol

Therefore, 4.77×10¯³ mol of AgCl was produced.

Next, we shall determine the number of mole AgNO3 that reacted. This can be achieved by doing the following:

From the balanced equation above,

1 mole of AgNO3 reacted to produce 1 mole of AgCl.

Therefore, 4.77×10¯³ mol of AgNO3 will also react to produce 4.77×10¯³ mol of AgCl.

Next, we shall determine the molarity of AgNO3. This can obtain as follow:

Volume = 91.9mL = 91.9/1000 = 0.0919L

Mole of AgNO3 = 4.77×10¯³ mol

Molarity =.?

Molarity = mole /Volume

Molarity = 4.77×10¯³ / 0.0919

Molarity = 0.052M.

Therefore, the molarity of the AgNO3 is 0.052M.

Finally, we shall determine the molarity of silver ion in AgNO3. This can be obtained as follow:

AgNO3(aq) —> Ag+(aq) + NO3-(aq)

From the balanced equation above,

1 mole of AgNO3 produced 1 mole of Ag+.

Therefore, 0.052M AgNO3 will also produce 0.052M Ag+

Therefore, the molarity of the silver ion, Ag+ is 0.052M

answer

fusion: the energy source of stars. the energy released from the collapse of the gas into a protostar causes the center of the protostar to become extremely hot. when the core is hot enough, nuclear fusion commences. fusion is the process where two hydrogen atoms combine to form a helium atom, releasing energy.
