Volume of Solution

Question

If 4.34 g of CuNO3 is dissolved in water to make a 0.580 M solution, what is the volume of the solution?  

 

?=ml

Answer 1

The molarity equation is Molarity = moles/Liters.

 

Given 4.34 g of CuNO3, we can convert that to moles using the molar mass and substitute it into the equation along with the molarity given. Then, we rearrange to solve for the volume:

 

4.34 g CuNO3 x (1 mole/125.55 g) = 0.0346 moles CuNO3

 

Molarity = moles/Liters

0.580 M = 0.0346 moles/x Liters

x = 0.0346 moles/0.580 M

   = 0.0596 L or 59.6 mL
