How many moles of silver chloride are required to make a 1.0M solution of silver chloride in a 100mL volumetric flask?

Question

I have no clue what I am doing please help me 

Answer 1

1.0 M is the same as saying 1.0 mol/L 

Volume of the solution is 100 mL we need to convert this to Liters, V= 0.1 L 

 

if we use the equation C = n/V

where:

C is the concentration (in mol/L)

n is the Number of moles of solute

V is the Volume of the solution in Liters

 

we can rearrange the equation to say n = C * V

 

n = (1.0 mol/L) * ( 0.1L) 

n = 0.1 mol 

 

AgCl is the solute so the moles of solute needed to make a 1.0 M solution of AgCl in a 100mL flask is equal to 0.1 mol
