Question

What is the molarity of a solution made by adding 1.565 moles of PbNO3 to 500 mL

Answer 1

[PbNO₃] = 3.13 M

Step-by-step explanation:

Molarity is a specific sort of concentration where we have, the amount of solute's moles contained in 1 L of solution.

In this case, our solution's volume is 500 mL.

We convert to L → 500mL . 1L/1000 mL = 0.5L

Moles → 1.565 mol

Molarity (mol/L) → 1.565 mol / 0.5L = 3.13 M

There also types of concentration, for example molality which indicates the moles of solute in 1kg of solvent.
