Question

62. To prepare a solution of concentration of 0.03 mL
of AgNO3, what amount of AgNO, should be added
in 60 mL of solution?
(a) 1.8 g
(b) 0.8 g
(c) 0.18 g 1 (d) 0.108 g

Answer 1

Answer:

a) 1.8g

Explanation:

Element = AgNO = Silver nitrate (Given)

Quantity of the solution = 60ml (Given)

Quantity in one ml =  0.03 g (Given)

Molarity is defined as the moles of solute per liter of the solution. It is equal to the moles of solute that are divided by the liters of the solution. The solute is defined as the substance which is being dissolved, while the solvent is the substance where the solute is dissolved.

Since, we need to know as to how much the solute should be added in order to make a solution with concentration of 0.03 g, thus -  

0.03 g = 1ml

x > 60 ml

(60/1) × 0.03  

= 1.8 g

Thus, the amount of solute to be added is thus 1.8 g.
