How many moles of AgNO3 are present in 1.50 L of a 0.050 M solution?
elixir [45]
To calculate the moles of AgNO3 in a solution, we need to know the volume and concentration of the solution. 
Moles of AgNO3 = Volume of AgNO3 solution (L) * concentration of AgNO3 solution (M or mole/L) = 1.50 L * 0.050 M = 0.075 mole.

So 0.075 moles of AgNO3 are present in 1.50 L of a 0.050 M solution.
